Thread: Pontiac 400 Stroked to 407 Engine Spec Sheet (correct numbers) Input / Advice Wanted

I commonly suggest putting the original numbers matching STUFF on the shelf for safe keeping and built a replica to beat the hell out of---that way if you do have something split apart in a catiscrpic manner you haven't killed the value of your ORIGINAL package??????????


But also, in those deals I don't recommend an engine of another make/model because of all the accessories, exhaust, etc------you can still show your Poncho at a Pontiac DAY WITHOUT ALL THE SNUBBERS turning there backs on you---------


and probably valve seat, valve spring, rocker geometry are biggest concerns along with the roller cam /modern day oils issues




Also OSK, I didn't realize that you had recently opened a SHOP?

Also yes I am pushing hard to get him to leave the original engine alone. I'd much rather go find another 400 to build and convince him to just store the numbers matching. I always try to side with what's best for the car first customer second. I decided awhile back I'm tired of working for others. Its much better working for myself!
