I built a 400 Pontiac motor over 20 year's ago.. solid flat tapit cam.. 6x heads. 30 over Forged pistons.. still runs great today.. countless 200 shots of nitrous.... 👍👍😎💯
Like going back in time for me seeing that motor. Pontiac 455 was the first engine I rebuilt back in the late 70's. I only wish I knew back then what I know now, lol! Nice job Rich 🙂
I`m not a fan of green cars, but that Firebird is downright gorgeous. You guys are keeping it real with oem parts for the T/A. Awesome job Rich, thanks for sharing Austin. Damn I wish I lived closer, if I did I would never turn another wrench on my own older junk. My 96 Blazer needs an engine, but I have never worked on 4wd. Had it been 2wd, the 4.3 would be on a stand torn down to find out what happened. I`m thinking a spun bearing due to the racket it makes when running. Bought it used last year for 500 bucks after it sat for a year. Old owner kicked her bf out and kept the Blazer. I love that thing. Ran great till it didn`t😁. I want to twin turbo it🤣. Stay safe all, God Bless.🙏
The OEM covers are now pushing 50 yrs old..I think if I were in your situation, I'd try a Repop from like Butler Performance. The newest OEM's would be from 1979..There just getting to old..When "Pin holes" were my problem...TWICE--Repops were not even produced yet..So its was just keep trying to find ANOTHER OEM & hope for best..Back then...@@LucoreAuto
As Pontiac purists we get it but that thing is a BEAUTIFUL mutt and there's no denying for a fact capable drag and drive style there's no beating a twin turbo LS.
Lucore are intelligent techs, they understand that the oil needs zinc, they know it has to be broken in correctly. Younger generations have no common sense about flat tappet cams.
No. It will work. And with a bunch of preload the lifters won’t pump up and blow the staple-like keepers all through the motor like mine did. First set I ever used. And last. I run Rhoads Lifters exclusively and they have never failed me in over 40 years. They have snap ring keepers. See Comps keepers retrieved from my oil pan on my Community page. First 6k blast that is where they’ll be.
