Rebuilt my 401 a couple of years ago. It required a 0.030 over bore so it has new pistons, cam and lifters and most internal parts. It has never smoked. The debris in your oil pan is unbelievable. Hope you have better luck with your current rebuild.
I have been rebuilding Buick motors since i was a teenager. Everything from a couple 215's to stroker 455 builds. Nailheads are not that hard to build. And they are bulletproof little engines. Im so sorry this happened.
I payed for a professional engine rebuild on my 1963 Ford 292 Y Block on my F100... Driving it home from the shop, I was accelerating from a stop and the carb just stayed open and it was revving and I couldn't stop it. I shut off the key, drifted to the shoulder of the road, and got a ride home. Long story short, there was a rock in the intake manifold that got jammed under the butterfly of the carb. A stone was inside my intake manifold. I think it was dumb luck it got lodged under the butterfly. I am fairly certain it was meant for the engine to ingest and destroy the valve, cylinder, and probably engine. I went back to the shop a few days later after getting the truck home and sorted out and there was a chain on the doors, a sticker on the window from the County Sherriff saying something about a seizure of the property, blah blah blah... I feel ya, brother, I feel ya. By the way, the engine was only cleaned and spray-bombed and it was never rebuilt. I was 20 years old and just trusted that the work was done.😕
I'm so sorry you had to go through this with your Buick. I'm in the process of rebuilding mine and I thank you so much for posting the videos. Do you have any updates on your engine? I hope whoever has it now has fixed it properly so you can enjoy such a great car!
Thank you for watching. I've been able to get the engine rebuilt again, and it is happy back in Sherman and we are cruising the streets. Please stay tuned for the next video detailing it!
God help you if you your engine received a BAD set of new lifters. Very common years ago when I rebuilt a 454. The damn lifters dissolved and this happened to another person working for an auto parts store rebuilding the exact same engine. Metal particles went throughout the engine wiping out the bearings and crank.... The supplier said they would send replacements??!!!
Sorry to hear, have watched your videos. seen how you installed motor great job, had a car like that in past now have a skylark, interested in where you are taking it, have 401 motor in machine shop now. Looks like just did not clean motor before assembly.
It's hard to find reputable builders on these vintage motors. Everyone wants to treat them like Chevys. Of course, they aren't; they are much better. Matt Martin and Tom Telesco are prolly the best in the business.
@@daryllect6659 My love of nail heads began in high school when I realized that my ‘66 could walk other muscle car V-8’s in our short backroads drag racing runs or stoplight to stoplight races where nobody really went over 50-60 mph. Just a testosterone guy thing for street credibility. That was where having peak torque at a much lower rpm really shined. Actual real-world usage on public streets. Not so much when it couldn’t breath punching it at 70 on an interstate, but who does that in the real world, right? Those small valves with port matching really increased flow velocity where it was needed. Flow volume was a very secondary concern for the big land yachts it was powering.
@@blackhawk7r221 The nail-valve Buicks are a joke. I street raced too and the Buicks were a loser. A good running Olds/hydro would demolish a Buick with their pathetic 2-speed Dynaflow. Torque is for tractors. Small block Chevrolets and Fords with a set of serious gears is the answer for the street. I ran 5.13s in a legit California street-legal 401 AMC that we built just to prove a point. Ran high 11s on DOT rubber @ Fremont. Our motto- "Build 'em light, and wind 'em tight"
@@daryllect6659 I’m not talking about drag strips or modified engines. Real world with broke ass teenagers. Just a stock GS with a 3-speed manual. I sure wouldn’t waste my time modding one for the 1/4 mile, that’s for sure. That’s what my long stroke 455 is for.

Wow! Interested to hear the outcome…
Outcome was that I was able to re-rebuild the engine for $2300. Original builder made some basic mistakes: ruclips.net/video/NWdG3UnpJJQ/видео.html
Sorry to hear this! Keep us posted on what they find wrong.

TA PERFORMANCE,AZ
The valves resemble nails, not the heads.
Sounds like a terrible saga. Good luck! I feel lucky now that my nailhead rebuild in 2017 went smoothly.
That sucks bad man. Sorry to hear that. :(

If you've ever had a nailhead Buick cylinder head on a flowbench, you'd never use it for a performance engine. The exhaust port is a joke.
It’s built for low to mid rpm torque, not high rpm horsepower.
@@blackhawk7r221 Kinda like a tractor...

Nailheads aren't like sbc or bbc. If it smokes it is almost always rings. Of course your experience is another example of this.
Great point!
I hope you have a better mecanicks now Rolf from Sweden
