I have to say, I've watched countless CZcams channels on engine rebuilding and related mechanics. And I have to say, your channel is by far the best! Your attention to detail and methodical procedures and tips are superior to ALL the others! I've already pinpointed things I've done wrong by watching your videos. I really appreciate you sharing your experience to learn from. And I appreciate that you reply to related questions in the comments.
Thanks so much for the great compliment J.R. It motivates me to keep going. AG
This channel has the potential to get a LOT of subscribers. People love engine builds and a LOT of people have a fetish to see engines run on a stand after it’s built. I’m surprised it’s not at 30K subs already and easily get to 100K subs.
Thanks for the encouraging words Willy. We are working hard to deliver real life knowledge and experience. AG
Golds is one of my favorite channels. Great down to earth info with no egotistical silly antics. The only thing I can critique, all the engines you build have the distributor on the wrong end.
Thanks Paul, we have a 340 Mopar coming up sometime this spring. Watch for it. AG
Great video lots of great info, like the Camaro in the background, I've had my 68 396 Camaro for almost 30 years having a blast with it enjoy your summer keep the videos coming
Thanks for your comments John. Enjoy your Camaro. There are a couple of videos about mine on my channel. I first bought it in 1969. AG
Unbelievable quality!! With hundreds of these videos under my belt I never thought I would learn so many valuable rules of thumb about starting of a small black Chevrolet. You have a very eager new subscriber, golf, clappage.
Very nice compliment Mr. X. Thanks for subscribing and commenting. Lots more to come. AG
Hey Alan,
Great content as usual.
At some point in the video, you mentioned filling the carb's float bowls before starting the engine. I know how to do that, but for your viewers who don't know, you can take a small squirt bottle of gasoline and squeeze the gas into the carb's vent tubes to fill the bowls if you don't have an electric fuel pump.
Good point Bart. I should have mentioned this in the video. I will try to include it in future videos. Thanks for the input. AG
Nice presentation on the start up.🏁🏁🏁
Thanks! 👍Thanks for your comment Steelcity. AG
Great video! Well done.
Thanks Graeme. The next video will be about the after break in diagnostics. Watch for it coming soon.
another appreciated video-thanks for taking the mystery out of installing the distributor
Thanks for your support as always. I have to get you into more in the future. Dyno day August 5. AG
Very beautiful yard!
Thanks Alleyoop. I have passed your compliment on to my wife Mariana who does the gardening. Watch for the next video on the break in diagnostics to be published soon, you are mentioned. AG
excellent work
Thanks Matthew. AG
Really enjoying your videos, not to knock anything at all, I am sure you probably did it already, but before installing distributor we can prime the oil pump with 1/2 inch electric drill so oil is right there ready to go. thanks for posting !! oh cheers from Calgary!!
Thanks for your comment Ken, Yes I do prime every engine with a priming tool and a drill. The tool is better than a drill because it mimics the distributor and prevents oil from dumping back into the pan and forces it through the lifters and push rods. AG
Awesome information.
Thanks John. AG. We will do a follow up with lessons learned. AG
Awesome video very informative and nice camaro 😊
Thanks Justin, we have 2 or 3 more videos in the pipeline, post break in diagnostics, changing valve springs and then on the dyno Aug 5. Watch for them. AG
@goldsgarage8236 awesome I will watch for these videos
Very methodical, clean work area and great starting stand. But please check motor manual, most Chevy V8 engines with a stock distributor have the rotor pointing to the boot terminal to the Left of the point adjusting window
This is important so that plug wire lengths matches this starting point on the distributor.
WOW THAT WAS A PERFECT VIDEO
Very nice comment, Thank you Hank. AG
Great Video!
Thanks Willy. We have more videos in the pipeline, then Dyno day Aug 5
thanks for these, really this is soon to be lost knowledge
Thanks Popeye. I am happy to share my knowledge as long as I can and someone is willing to learn. AG
JOE yes you can turn the engine over to allow the oil pump rod to mesh with the distributor put light pressure on the distributor to make sure the cam gears do not miss align putting it out of time, the rotor will turn keep your hand clear, hope this helps.
Thanks Fred, good description of the process. AG
BRAVO 👏
Thanks Jimmy! AG
Building a motor , on my bucket list.
Thanks Gene, We can help you with that. Please keep watching. AG
When I built Jaguar engines I used to start them initially without headers after dark. The colour of the short flames will indicate if all cylinders are working equally well. Also, while tappet failure is no issue with the Jags, you still need 2000+ RPM because at idle the piston rings can glaze over within the first few minutes idling preventing them from ever seating propperly. The enginge will burn oil for ever. Only another tear down, new rings and often a new hone can fix this.
Thanks for sharing your experience Patrick.AG
Hoping you can detail wat goes into building an engine run stand. Thanks for your videos.
Thanks for the suggestion Brad, i will work on that. AG
Nice start up. I never thought to use hot plugs. I have used cold ones, and had the carb safe rich and I am surprised it ran. I had to tear the thing down, within 30 km and the chambers and plugs were soot! Safe rich, that's a bit rough! So it gets warm up North for a few days? Nice street and garden.
Thanks for your comments MsKatjie AG
I almost forgot. An old bloke years ago, asked me why his Clevland would not start? I said, " every 353849 idiot knows Clevo's turn anti clockwise. The dissys, that is. He left without another word. A grunt was my thanks. Cheers.
Cheers back, thanks for commenting.AG
Sounds pretty mean 👍👍👍😁
Thanks Medium. Not a big cam but the narrow LSA will help to improve the sound. There is a short on my channel of it running without the mufflers. AG
Nice video. 👍
Ive also heard that if the engine have a windage tray it should not be used during first start up. Any thoughts on that?
Good point Magnus. You are correct that the windage tray will prevent some of the oil from the crank and rods splashing on the camshaft.
This engine does not have a windage tray, however the last 400 that I built did have one. It started it with the tray and had a clean start with no issues.
That said, removing the try for start up is probably a good idea. AG
Hey great video! You said you can use any gas to break a cam in no matter the compression. I’m building a 13-1 compression small block with dome pistons, can I just use pump gas to get the cam broken in? I will run the car on race gas for racing but it would be good to know I could use pump gas for a break in.
Important question, thanks for asking. When breaking a cam in on the test stand or in your shop, the engine is never under load so it is fine on 87, however if you are driving the car and loading the engine, use the same fuel that you would for normal driving. AG
Love your videos where are you out of
Thanks Mario, glad you enjoy them. I am in London Ontario Canada. IT is about half way between Toronto and Detroit. AG
Growing up in the 60's, I watched a few neighbors working on their newly rebuilds and not running at or about 2k RPMs for break-in, most of them would just get in, crank it and drive. Maybe that is why most them were back in the engine in a short time. Cam break-in is the most important item that just was not common knowledge at the time, when did mechanics realize that you need the break-in on a new cam and lifters?
Hey Brad. Two things happened in the late nineties. Most OEM's had switched to roller cams. Zink in the oil was damaging catalytic converters and it was not required for roller cams so oil companies stopped using it. the problem is they never told anyone.
Because OEM's were no longer buying millions of flat tappet lifters, many of their suppliers stopped manufacturing them. This opened the door for less equality lifters from questionable sources to enter the market.
I think most flat tappet cams are still made in the USA and i also don't think the cams are the problem most of the time. The lifter is more stressed than the cam and i think is typically the original cause of failure.
In 1973 I put three different flat tappet cams in my C/MP Camaro (starting at about .515" then .550" then at about .580" each time just for more power. i reused the lifters all three time and paid no attention to where they came from. Never had a problem. Sometimes what you don't know won't hurt you. AG
Pro Tip, if you put that slot in the oil pump shaft at 11:00 and 5:00 o'clock the dizzy will go all the way in! No need to crank engine to get it to drop!
Thanks Doc, good tip. I have done it that way as well. Thanks for the input. AG
I just saw you added me. I don’t ever post anything in here. Just have some saved music. I probably should start shootings videos since I do have a lot of projects. Lol. But for a video you kind of have to work on them right? At this point I’m watching most of them rust waiting for my son to catch the hot rod bug.
Thanks Rick. AG
I always turned the oil pump slot by hand to get the distributor to drop in, but you turned the engine over to do it. That confused me because it would seem the engine isn't at tdc on the compression stroke on number 1 cylinder any more. But the engine fired up so I have to figure that one out.
Good point Joe. As long as the distributor drive gear is engaged with the camshaft gear, they will turn together and the rotor will still be in the right place. AG
@@goldsgarage8236 Ok, I didn't think of that. Seems every time I watch your channel I learn something new.
Should you use a push fan or pull fan dirt car stock car would you know Thanks
interesting question Patrick. I don't run a dirt car but I think you would put it where it is less likely to get damaged or clogged up with dirt. I don't think the engine cares. I am not an expert on this subject, so I suggest you seek other opinions as well. AG
Does a hydraulic Roller cam also need a break-in ? Thanks in advance. Captain Keith Tight lines
No Kieth, If you prime the engine prior to start up you’ll be fine
@@goldsgarage8236 Thanks for your speedy answer. I find your videos very informative, keep it up. Captain Keith Tight lines
What oil are you using for your break in?
I use Lucas break in 30 weight oil with ZDDP for break in, always with good results. AG
The engine running at 2500 rpm will get plenty of oil to the cam. In the meantime, while you are standing there revving the motor up and down like a 16-year-old that just cut the muffler of his Cavalier you should be walking around looking, listening, and smelling for any problems. If you shut the motor down before the full break-in time is up, you have to remember that you have washed all the break-in lube off the cam so when you go to start it again, you have a chance for a lifter to gull the cam on the start-up rotation. One other thing, if it is taking 15 minutes to get to the temperature you must not be running a thermostat so the oil isn't getting up to temperature as fast as it should. Hope it does well when you dyno it.
@nojunkwork5735 I agree with everything you said. What I don't agree with is Golds Garage's theory about having to heat cycle the gaskets without a radiator cap. I am not sure what he thinks is going to change doing it that way. But watching the video he seems to be full of old wives tales and overkill on his build.
Do you soke your lifters before install?
Yes I do, however it is not necessary as long as the engine is primed before starting. The priming process will fill the lifters with oil. Thanks for the question. AG
So much money and time in these builds at this point in time with problems with flat tappets I don't think I would build a motor with them... Either retrofit lifters and cam or factory roller lifter block. So many horror stories on flat tappet builds going south!
Thanks Larry for your comment. Roller is definitely nicer and safer for sure, but they are quite expensive and would never fit into a Budget Build. I have never had a failure on the stand or on the dyno, however I have ideal conditions and go to extremes to make sure it doesn't happen. AG
Elgin cams and lifters work great
How do I fix the 8 to 12 volt problem ?
Prior to about 1973, cars with ignition points used either an in line resistor or a resistance ignition wire to reduce the voltage from 12 to about 8 volts. If you run a direct connection with a non resistance wire from the ignition terminal, or any 12V source that is "on" with ignition, directly to your coil you will have 12V. Hope this helps. AG
I don't think it was mentioned, but, before you attempt to start a fresh flat tappet cam engine, make SURE that you have the timing correct (not 180° out), fuel bowls on the carb pre-filled, cooling system full and ready, belts on, etc. Be SURE that everything that will let the engine just fire up on the first few revolutions and run, is correct.
Even extended CRANKING before firing up CAN increase your chances of an unsuccessful cam break-in, and flat lobes in the near future.
PROPER oil with plenty of zinc is of utter importance also.
I won't even mess with a flat tappet cam anymore. Roller cam, or NO cam, for me..
Sure, they cost more, but the benefits are completely worth it to me.
Lots of good information. Thanks for your contributing to my channel Dave. AG
He explained exactly how to install it correctly
Elgin cams are fine
I have a question I am looking to build my first engine and will build a test stand first but I would like to know what brand cam and lifters you use in this small block. This engine I am building is a 327 it is a practice engine to put in the car to be able to move it in and out my way while I am building it but I will be building a 383 after that. I don't want to buy a roller cam just for a practice engine but I will be putting a roller in the 383 thanks.
Mike, I know you have the part numbers in your head, can you answer this for me please? AG
hello did Mike get the info on the cam and lifter brand you guys used on the small block rebuild thanks
I will get back to you shortly. AG
The cam is Crower 00256. AG
and if you do not mind my main concern is the lifters have you ever used the new comp cam lifters with that special coating on the bottom of the lifter. So what name brand lifter did you use in the build. The reason I am asking is all the stuff I am reading about how the lifters and cam you have to make sure they are machined right so you don't wipe a cam. Thanks for answering my questions
Love everything you do but PLEASE put all the flywheel bolts on!!!!!
Thanks Doug. The only torque on the flex plate right now is the starter, but I will have all the bolts on for the dyno. Good catch and thanks for your input. AG
VOLUME! PLEASE
Thanks Brenda. I did re-listen to this video and the volume seems ok. Sorry you are having trouble hearing it. We will work at getting better. AG
Oh man buget buid today ...if good NOS parts are used instead of Comp or China crap means 10.000 Euros spent at least...
Liters??? Is that french??? Whats a liter???
It's a unit of volume that the rest of the world, except the U.S., uses.
3.785 liters = 1 U.S. gallon
@bartsarton2212 ya, I was just playin. Lol!
Thank Jesse for injecting some humor into the subject. AG
Ever get any rude hand gestures from your neighbor's wives whilst you're breaking in camshafts?
That is funny Yarrda. I usually run the engines with mufflers and I am respectful of time of day etc., but as far as I know most of them like it. As you know if you are a car guy, it is music to your ears, of not, it is just noise. Thanks for your comment. AG
We got a 11:1 350 Chev in a Chevelle fired up at 2AM. Probably half the town got woken up as it was in the garage that acted like a concert hall. Buddies mom came out in her house coat and a broom and started smacking noggins. This was at the time leaded fuel was being phased out.
That is a good story Dale. Back in the drag racing and Super Late Model days in a different city sometimes we had to fire up in the middle of the night. I have had a few visits from the police over the years. Most of them liked it too! AG
