As you all might remember, a while back we had an extremely rusty 396 Big Block Chevrolet engine come in, and we installed repair sleeves in ALL 8 cylinders! Well, the heads for that engine were also rusting away, but we're going to change that!

I'm just so ready for your dads tractor rebuild video. I love how you guys are showing it and are humble about what has happened. Most people would just blame the kit but he is going over everything he checked and even saying what he could have missed, you can't walk though the ranch and not expect to step in cow 💩 really once in a while. Also explaining what has happened.
Another update coming on Sunday, and then hopefully it'll be running by the next!
@@JAMSIONLINE that's great bub. I can't wait.
@@JAMSIONLINE Cant wait either best content I've seen
Believe it or not I find your narration of your work very pleasing, your dad also is wonderful to listen to as an ex engineer it is just a nerd thing to hear details...
Please keep up the great work and I hope your channel inspires others because we will have gas and diesel engines for a very long time.
It's great to see during your ad for the sponsor you displayed Blinker Fluid. One of the most over-looked essentials for any road-worthy vehicle. As a truck driver, I am amazed at how many vehicles on the road are dangerously low on blinker fluid, or they are using the cheap stuff from a discount store. Always buy a good quality blinker fluid from your local auto parts store!
Muffler bearings are an overlooked item too.... I recommend all women on here go to your parts store and ask about them...
the Heavy Duty ID10T formula for Blinker Fluid ?
@@JohnH20111 Purchase from your local dealer. Available in quarts and gallons. Quantity discounts available.
@@kenore4003they really do, I once had to rebuy all my stock because I accidentally spilled it into my elbow grease drum
No guys, regularly replacing your piston return springs is way more important than that stuff.
Its so sad how many machine shops are closing, I bought a complete shop last year it was the ninth shop to go out of business in my area,l just couldn’t let it get pieced out. I worked in a shop several years ago but had moved into building street rods and sixties Chevys, so I guess I’m back to where I started. Thanks for your videos they are a great refresher so I don’t forget the little things.
A high standard of workmanship. Thanks again for another great tutorial. Be good. Stay safe. Wishing you a Deluxe week!
Idk why but I love the sound of properly sealed valves making that "thunk" when they slip into place...👍
They "thunk" on the intake side but "think" on the exhaust! 😉
Good 'ol closed chamber BBC heads, you could make some serious compression back when great pump gas was available. Time and technology have made the open chamber and corresponding piston design the way to go. Thanks for your time guys!
That Slo-Mo of Cast Iron Chips coming off that Cutter is very satisfying 2 me. 😯👍🍻
I enjoy your work very much!
Last time my big block Chevy was in the machine shop, the gentleman who owns it let me assist with some of my assembly which was fantastic as nothing was more satisfying than having hands on experience.
Keep the great content coming. Everything you do is impressive 😃👍
If a person has never rebuilt an engine, the cost of machine work can cause a little sticker shock. Channels like this one perfectly illustrate the amount of work involved in getting an engine back to operation.
Had a great machinist that I grew up around and taught me a lot, you and your dad have that same pride and attention to detail that my old friend had. He passed away and I moved, I've yet to find another machine shop near where I am that comes close to having his level of expertise. Kind of sucks having to cross state lines to get certain things done but I'd rather it done right than trade convenience for regret. You and your dad are part of a dying breed, true masters of a trade.
Nice work as usual! You are correct, time was, there were competent machine shops within 25 miles of most areas. You are way beyond competent! What quality!!
i think 🤔part of the problem for it becoming less is car's are disable/cheap to buy ( not explanation rather well sorry im trying ) but typical after about 5yo gets to be more expensive to owning vs just getting a new lease ( and as much as i like older car's some aren't worth it and or the metal has fatigued-out ect ) and the average person/30yo nowadays has more accesse to loaning/credit card's ect and spare income is lower and or most don't have 1k usd ( emergency's or disable/fun-planning-$$ ) to spending or the time needed bigger auto-repairs, heck i met people that moved out/sold their ( generally a newer home aka not 60+YO ) house just because of the AC broke/leaking ( aka sub 500usd repair or so ) , me im like okay big deal at least my "house" ( don't own anything property-wise aka forced sofar in to rental's and lower income's/slum-lord's one's at that ) is pay'd-off/no need to move and il get around to fixing it someday...
and for me/88-90's-kid personally id rather have my engine 4.3X4.5"in D8-head's rebirthed but i don't have 10-30k usd that it needs to be 👌but so far iv been without my car/1969 charger for over a year now ( insurance was supposed to cover at least for the thefts/vandalism ect but so far im stuck paying for legalised fraudsters/insurance as they haven't paid anything yet 😡, i just wanted my car/dreams back not the debts or $$ or headaches from the joyriders that started the mess ) but even if $$ wasn't a problem it would have been at least 90+days as the shop has to order in and waiting and then i have to waiting for them ( and transfering thing's like heads and block aka heavy stuff that can't be mailed so id have to do it my self ect ) ect before i can R&R the engine-bay ect
You and your dad are that certain type of person (like Adam Booth (abom79)) where things need to be to your standard. It's great to see skilled people taking pride in their work.
Engine work is so interesting because there is so much detail and knowledge required.
BTW do you guys do porting and flow testing?
Don't currently do porting and flow testing, but would like to eventually!
Lots of Stor-loc cabinets around your shop.......Nice. I use them in my home shop. Made in the USA. I like that.
I am a huge fan of this 396 rebuild. the baby big block always one of my favorite engines. nothing beats the sound of a 396 with a mechanical flat tappet cam. growing up in the mid 80, my uncle had an early 1970 Chevelle SS 396 L78 motor. that thing was amazing and incredibly fast. I am currently building a 1971 Camaro SS 396, but swapping i a hydraulic Roller with specs similar to the old L78 cam, but now a hydraulic roller simply because i want to be able to you off the shelf motor oil and not worry about the cam going flat, and I hate adjusting lash all the time.
You do a great job all the time and I’m impressed of you always trying to do the best job you can for the customer.
One thing I react to is that you often don’t protect your ears.
Be careful because hearing can’t be repaired when you get older and the damage starts to show.
Love watching your channel. Brings back fond memories of my days working in a machine shop. Kwik-Way guide and seat machine was the hot lick in those days. Long before Serdi was on the scene. Kwik-Way FN boring bars, Sunnen was the king for rods and cylinder honing (cylinders by hand, giant 3/4" drill suspended on a spring!), Storm Vulcan Block Master, Van Norman, Berco, Borg Warner (balancer) were the tools of our day.
Greetings from Greeley CO. Always good to see a local business do well and be youtube posters!
Love your channel!! So good to see people do excellent work in a world of throw away/slap a reman part in it!!!
Another great episode! Keep up the good work and sharing it with us.
Your videos and a fresh cup of coffee are my favorite mornings
No rest for the wicked at jamsi
Super job with the sponsor segment. The split screen is a nice way to do it.
These oval port BBC heads are great heads for the street.... Lots of torque and power......
It's amazing watching you doing this with the specialized knowledge, machinery, and fixtures you have. I shudder to think what this cost you and what you have to charge the customer. It also makes me wonder if one wouldn't be better off buying a modern crate engine to retro fit in the car. Of course, it would no longer have the collector value.
This just popped up for me. Really cool seeing the work go in. We would just send heads away and would get them back completed with no idea the process. 👍
you right about the diying industry, we have no machine shops left in our town,I've seen 3 close over the years, i cant get a head skimmed anymore. and tell your dad not so much nitrous in the tractor next time.
Cleaning guy's job is NEVER done!!! Loved the video.....
Always love the slow mo valve bounce.
I have that exact set of heads ready to go. Nice work gentlemen!!!
Ahhh, The Big Block Chevy, what a great engine. I remember when I wanted a HP 454 street engine, my racing buddy insisted we do head porting and flow matching...on cast iron heads. That's 80 hours worth of grinding and testing I'll never get back. But it did add some power, I think, lol. We made 605 hp NA on the Dyno.
If this one runs as good they'll need good tires. :)
Milling Heads in the Wee Hours of the night, is a sure sign the Clean Up guy needs to THROTTLE BACK on those Power Drinks...
Interesting process . Thanks for sharing .
I would love to be able to do this stuff. Skills involved are so interesting to me. But do you ever see the final assembly or maybe running engine? Or is it pure measurements telling that this head or block is ready for assembly?
I love watching these machining videos!
The quality of your work is perfect! Those cylinder heads are going to be perfect! Nice job sir! Great video and thanks for sharing!
Highly professional work.
Thank you for another informative video. Very well done.
12:20am, wow you're working the poor cleaning guy ragged! Heads look great👍
Another great video! Thank you so much!
It's lovely to see the great relationship you have with your father... very envious 👍
I really like your guys's cleaning process set up
Really enjoys your videos fellas.
Great way to do the add brother
I actually wAtched and didn’t skip.
The cleaning guy. 🤣🤣🤣🤣
you two are incredible. good work
Gosh, that cleaning guy could stop by and do my garage anytime after midnight!
Great work guys
Your shop does good work. Fortunately I have a shop in my area that does the same quality of work.
Great video as always!
Good video. That Serdi machine has quite a beefy spindle, I'm sure that prevents deflection and allows you to place and ream guides better than the factory
Beautiful machine work.
Love y’all I’m a motor head. Love learning about how to fix anything
To be fair, 25% of viewers being subscribed is very high compared to many other content creators where it is only 10-20%. You guys have a lot of people that really enjoy the content.
You guys are great. Shop is clean. I wish you were local.
You are so lucky, I always had to use those quickway seat cutters each angle by hand.
Nice work as usual.
Keep old school alive buddy love it🇦🇺🍻
Nice work i wishi had all that machinery
Great work 👌
Love your machining content
Great work
Job nicely done.
Very nice work! You used a knife to make sure the machining had not compromised the water jacket surrounding valve seat. All was well, but what would you have done if the water jacket had been compromised? Thank you!
Love all your videos
I'm subscribed and I really enjoy your videos guys, nice work!
I noticed you used lube on the exh seat removal but on the intake none.
Are the exhausts induction hardened and not the intakes or does use during operation result in a hardened surface due to extreme exhaust temps?
Ah man, I wish I knew this is the type of job I should've gone for way back when I had no clue what I wanted to do as a young adult. I want to put rebuilding (with assistance) a small block v8 on my bucket list, just need to find where I could do that :)
Late night fun with Dad😂 Thanks gents!
The cleaning guy has taught you well!
I bet those heads were that rough when they were new. Castings back then we’re rough. I seen on one guys channel that was porting some heads had a flaw in the intake runner that looked like a peanut shell sticking into the port. That 3 angle job outta help it out a bunch!
You’re a friggin artist.
Your old man is a legend
Another great one but it would have been nice to get a description of the options you'd have if you did cut into the water jacket from the seat pocket (@5:46)
Nice work on the 396 heads!!!!! Keep up the nice machine work that you guy’s do. Love your youtube channel.☺️☺️☺️👍👍👍👍🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸
Is there a port and polish video in the future? Would love to see the work it takes to extract more power from stock heads.
Those intakes did look like they were begging for some work. I had those same heads with larger intake valves so the pockets could be blended and they worked really well. The Oval Port heads flow just fine for most street applications and if you build an 'enhanced' 350 horse 396 they'll surprise most people as long as you don't kill it with too much gear. Let the torque work and also don't over-cam for the 6000 rpm redline. I know it sounds really small for modern minds...but something 204/214 @ .050" and about 1/2" lift is more than the 350 horse 396 had stock and is enough to feed it while allowing it to make all the torque it can from idle up. Put a good 400 Turbo behind it and 2.41-2.75 gears and what a nice package!
I wish we had good machine shops where I’m at. We just have tweakers who do horrible work but charge ridiculously.
A machine shop in my town hired a guy I graduated with. When we worked on our engines, he'd cut every corner he could. Can't imagine him going to the amount of detail your shop does.
I wish my father listened to me like yours does !
Looking good 👍
Was this done for a numbers match engine? Great videos, looks like a 350 hp head instead of the coveted L78.
Yes. He even has a video where the block was machined especially to avoid machining off the factory numbers.
Those are actually rare 65-67 396-427 oval port closed chamber 98cc. Casting #8872702!
Exceptional machine work!!
You guys are great ! I don't need a motor but having you build me one would make me feel better ! Lol
Love the content, the distracting 30 minute announcements should be saved for live streams.
I really wish you guys were here in Florida
Notification squad Have a nice weekend!🔥🔥🔥
Chevy called their newer big block heads, ”porcupine heads” thus the splayed valves. How do you make them concentric?
I really enjoy these videos. It's a good idea to dress the head of that driver you use to install the valve seats. It's looking a little 🍄
The valve guide and seat issues on an iron BB Chev are well known. I made the dumb mistake once of knocking out an exhaust guide from the top side down into the chamber side. Stock guides are different sizes on their OD's and stepped. Knocking them out in that direction can crack the head at the boss at the bowl side and may leak water. Sleeving the original guide is a much better way to go. GM did some really odd machining when they built those BB iron heads.....Just look at the guide holes and sometimes they are not concentric by a lot.....Just like how they located cam and crank centerlines in many blocks......way off center in the casting ! Those heads and the block were nasty but I assume the owner is wanting to keep the original's......Nice work ! I spent over 10 years doing engine work and I'd be happy if I still was.......never had as much good equipment as you do but we got by.......I'm very interested in the tractor engine story. That sure is/was a difficult one to diagnose and fix with confidence.
It’s awesome you get to work with your Dad, doesn’t happen very often nowdays, i think you ought to have some gand kids and take the reigns
Hot damn I love this stuff.
Please do a technical video on the valve spring setup
When you get to my age... "where do you want to be in 5 years?" Still retired. "where do you want to be in 10 year?" Not dead. :D
You definitely earned your sleep, Mr. Jim. I hope you rested well. I'm curious to know what all of that pitting is going to do to the air/fuel mixture on the intake side and the carbon buildup on the exhaust side.
The cleaning guy... XD gets me everytime.
When you originally brought the idea of a CZcams channel to your dad, what was his initial thoughts? I’m sure he thinks it was a great decision and I’m hoping that your efforts have paid off with a growing clientele base.
To be honest, he wasn't really a fan lol. He's old school, didn't really understand the world of social media / content creation. Now he's excited about it haha "You should make a video of this! When does the video go live? What's the video about this week?" haha
@@JAMSIONLINE I'm really glad you decided to make videos and that I found your channel. It is very difficult to find a machine shop that specializes in automotive work, let alone one that takes such care and pride.
After all the hard work put into those heads, a stock cam would be an insult, in my opinion.👍
The cleaning guy...LMAO
BBC guides are a pain in the a** lol. I do the same thing and just drill them for a .500 OD guide or put liners in if possible. I do like the tip of cutting the tops off before you drive them out, that's a good idea, don't know why I never thought of that lol. BTW how you guys like the Serdi 4.0? I'm actually looking at one I may buy. I'm still using a PH2000 for guides and hard seats, roughing in with the 3D system and Serdi cutters and finish grinding the seats (Standard steel fixed pilots are just not all that accurate on my 3D system). I'm tired of cast iron dust up my nose! 🤣🤣
Awesome video, and good looking work guys!
