- Today we are diving into how to rebuild an engine for my 72 challenger for under $100. The engine in question is a 1969 383 mopar big block. This engine was a marketplace engine that "ran when parked" and now its my job to tear it down and rebuild it for as cheaply as I can. we need to get this big block ready to race in a few weeks so we don't have much time to waste.
We are going to be ripping apart the block, pulling the pistons out, pulling the crank out, cleaning the block and clearing the oil galleries. then we will do a quick hone job to deglaze the cylinders in preparation for new rings. We will then set crank bearing clearances, install the rear main seal, drop in the crank, install the main studs, drop in the pistons with the new rings, torque everything down, install the camshaft and then the cylinder heads before closing everything up. the process took a few days while I got a few parts but I think the DIY engine rebuild was well worth it.

This is the type of vid I like to see. REAL WORLD BUILDS. 💰💰✅
@@TheProchargedmopar and theres more to come 💪👍
Great observation about the crank position and oil flow. It’s important to know this because when the heads and rocker assembly is on you won’t get oil flow to each head until you rotate the crank aligning those oil passages while spinning the pump. I always rotate in small increments while spinning the oil pump till I get oil to each rocker assembly.
I noticed that. As i was priming and turning, only 1 head was geting oil at a time 😂
That’s kind of a quirky detail about the Mopar engines. I’m 53 years old and I only learned about that detail within the past year! Of course I’ve never personally been inside of a Chrysler engine. I’ve only owned Chevys and Fords. Not that I ever had anything against them I just never had the opportunity to buy one. I’ve ALWAYS wanted a Duster or Demon because my cousin had a purple 1972 Demon in the ‘80s when we were in high school.
It will be a miracle.
Great video! Can't wait to see how it performs!
You might find out in person!
@@nightwrencherperformance looking forward to it!
@@PontiacRaysGarage 😱
Those ring compressors are such a great tool to have on the shelf. You may not need it regularly but, they’re cheap and will save you hours when the time comes.
Definately, I was always feel like buying the solid ones but this one has always worked well 👍
That's my ring compressor of choice!
Came out nice! Good job.
You already know how I work 💪
Good stuff. It's nice to see someone do a garage rebuild. Not everything has to go to a machine shop. We just did a garage short block too.
Thanks man! I think not a lot of people realize that you dont have to replace every single little part for a basic rebuild
I have done some engines like that and they ran good. Not too often you see an engine run without exhaust manifolds/headers, that was a great video!
Its typically not a good idea because it melts plug wires and sounds bad but I couldnt put the engine on the floor with headers 😂
Ran great when pulled. So I left it outside in the rain and snow for couple years without covering it up and oiling it.
We must have bought the same motor or something because thats exactly what happened 🤣
I enjoy the low buck builds like this.
Good video and great explanations!
Thank you! I have plenty more coming up!
Honestly man I’ve brought engines back to life just honing the glaze off and cleansing the shit outta everything…in a pinch you can literally hone the cylinders to a larger bore if you need to up the piston size…it’s tedious, time consuming and maddening but it CAN be done, I know I’ve done it. The key to a good rebuild is cleanliness and not reusing scored materials on the rotating assembly
Definately. If you know what you're looking at, you can really save some money on the rebuild. This 383 is in better shape than my 361 was so if my 361 took 14lbs of boost without breaking, this one can easily handle more now 😂
LOL, The famous Craig's list and Market Place posting: Ran good at time of engine pulling. Doooooh! Sure it did! lol Great Video NW, fun and helpful. Cheers from Motown, Home of Detroit Muscle!
At least you know what to expect! Typical marketplace!
Good thing you double, triple checked your work. Sounds great 👍🏼
I double and tripple check your work too 😂
Great done...simple and nice 👍
Thank you sir, I appreciate it!
Shitcha man good stuff!
Thanks man!
Nice
Thanks man 👍
Hot water and dish soap is the best way to clean the bores. Wipe them dry and oil right after cleaning.
Yeah, thats a good idea too. I dont have water at my garage so I gotta use the other stuff, mainly gasoline 😂
NGL. Love those blue flames. 🤘
They were pretty sick huh 🤘
Great video, getting ready to start mine
Oh nice! I hope it goes well for you! I'm dropping this engine into a car this week 👍
Very well done sir😊👏👏
Thank you 👍
Genius
Good video and it is good that you showed us your mistakes and what not to do as well. The problem with the new camshafts and lifters as like everything else these days most are made in China and as of the last number of years have had poor quality control with many of them getting destroyed upon break in.
I dont like the hyd flat tappet cams but thats what I got and it hasnt failed me yet 😂 it has a decent profile so hopefully it survives it little while in the 383.
Very cool.😊
Thank you Jim!
23:46 I am very skeptical of you doing this but I am going to be quiet and watch. Been doing what you are doing for 40+ years.
That I did what? Put the lifters in one by one while running the oil pump?
@@nightwrencherperformance I have been enjoying watching you do what you are trying to do and figure out without the proper equipment and I was flash backed back to when I was a young man, 14 and my grandfather, great uncle and grandfather's brother running the old family farm and they would get stuff like that old block you got from Facebook marketplace except they would get stuff from bartering, horse trading, hay/straw trading or swapping for the stuff they mostly needed except for the things that they found out at the Fairgrounds, or Farm show swapping meets and shows. They would always afterwards if they needed anything else it was the hardware or parts store in town about 9/10 miles away from the farmhouse.
Your technique works but it's extra work and trust me I triple check anything and everything, I would rather do that with the amount of those and transmission repairs that I do. I understand completely. I'm a do it once check three times.
I believe that it will be a good runner when you get it back together! I’ve seen guys assemble engines with every part machined to perfection and operating room clean and they had some type of problem with it. Then I’ve seen guys put together engines on the garage floor without checking the first clearance and they ran like a scalded ape and lasted a long time.
I think you're right. Ive definately built worse and made good power in my day 😂
Sounds good, did I see your dog run off when you started it lol
Yes 😂 he's an import guy and doesnt like the sound of a V8
Yep....I'm doing a similar deal on my channel but its a 318 going in a Coronet.
Very cool. I like the SBM, they're zippy little motors.
The rear main would have been good if you would have paid attention to how you took it apart.
This engine did not have a rear main retainer and I pulled the one off the 361 a few months ago so it was one of those details that is easily missed because it LOOKS like it goes one way, but it actually goes the other way
U honesty just needed to strip the block and used super clean from Walmart and honed it and then degreased it again after wire wheeling it and taken the time and done it right... The cleaning of the motor is paramount and the life of the engine... I do this all the time and reuse stuff like u but I can school u on a super clean block and all the passages
100% right, you can never be too clean.
Had no clue you had this channel until today. Is the old channel discontinued? Great to see your videos again
Hey man, good to see you! Nah, the old channel is still moving but this channel is for like vlog stuff and the other one is for videos for teaching different topics. I have a new video releasing on the other channel soon 👍
😎👍
Thank you Mr. Mopar Nut 👍
Never use silicone on freeze plugs bad idea
I've never had an issue using silicone on core plugs. I use permatex ultra black it's antifreeze safe.
Who taught you how to rebuild a motor?
No one 😂 Just watching youtube videos or looking it up online every time I wanted to change something until it just kind of clicked
Hi lick the way you rebuild a Mopar the way it should be done I built a318 my tools an all engine parts super clean 240 hp at r w an 625 fpt rw in 4th
Thats awesome man, tons of torque in that little motor!
how does a used block have too tight of main bearings or did i misunderstand that part?
I think you may have misunderstood what I said. If you can tell me what exact time in the video that you're talking about, I can clarify it for You.
@@nightwrencherperformance just goin by memory, i think it was about plasty gauge only reading one/1000, which means it didnt get squiahed enough so the bearings would be TOO LOOSE
@@WilliamMunny-d8s What I said was that I reinstalled the same bearings and did not have the crank polished so with the fasteners at the stock spec, the crank journals were around 2-2.5 thou, which is good but since I installed main studs, cranking down on the main studs, the tolerance TIGHTENED UP to about 1.5-2 at the higher torque spec and that the clearance would have been too tight. Ideally, I would want to set the clearance around 2.5-3 thou. The only thing loose on this engine was the piston to wall clearance which ended up around 5-6 thou. I hope that cleared things up, but if you have any more questions lmk.
@@nightwrencherperformance ok, gotcha
I prefer to oil my rings and bore first
Lubing it with break in oil is a good idea for sure
And no windage tray bad idea on 383
Im not sure if you noticed but I'm using a moroso oil pan that has a built in windage tray.
Yes I saw that your doing a fine job brother keep it up wasn't knocking your work at all I'm glad to see a young man working with my favorite engine 383 I noticed the oil pan after I commented my bad keep up the good work buddy
No problem, I appreciate it! The oil pan got switched out at the end of the video and it was never mentioed so it wasnt super obvious.
Ps lm a Australian the car 1972 vh valiant 4 door
Doing things in Australia definately makes things more difficult since getting parts delivered to that big island is not that easy.
Thats way too much gap on those rings.
How much gap do you think it should have?
Not for boost or nitrous…for a high rpm flat track motor who the hell cares
@@nightwrencherperformance it’s fine especially for the type of build you’re doing
@@localenterprisebroadcastin5971 Exactly. At least somebody is using their noggin.
@@nightwrencherperformance well some of us grew up throwing giggle gas and turbos at 200k motors to send em off the proper way…strangely the older worn out motor handled the stress much better…this was because the rings were already worn out and had no problem dealing with the thermal expansion 🤣…was there tons of crankcase pressure? Sure was…but it didn’t matter because we routed the PCV system to the turbo intake 🤷🏼♂️
Well there is clearly NO performance here on this cheap junk channel.
What were you expecting? A 10k engine rebuild? I'm still gonna make 5-600hp on this motor just like I did the 361 regardless 😂
