Any steet stocks out there using the stock Pontiac 350 big block engine? There's a guy at our track who has one and just destroys everyone else out there, no one can catch him. Are these engines capable of much "bigger" horsepower than a stock chev 350?

it depends on the heads they are using. i ran a pontiac 350 for 6 years and won a championship with it. i never felt like anybody was faster than me. the drawbacks are they are hard to find parts for and they are more than 100 pounds heavier than a chevy. i would spend 1400 bucks to get a pontiac 350 long block built. after 2 races on my $2400 chevy 350 long block, i like the pontiac better. pontiacs make alot more torque.

I would be checking this guy for displacement. All Pontiac blocks are the same 326" through 455". From the outside there is no way to tell what the engine is other than casting numbers. The big ones can be very powerful even in stock form. It takes a very expensive chevy to run with the virtually stock 455's at our track.

FYI the 400 and the 350 look identical unless you know casting numbers you can't tell them abart a built 400 will smoke a 421 down the pipe with proper gearing it is all in how much you want to spend the parts are their or they can be made

Another advantage to the Pontiac is you can get stock head with as large a 2.11 intake and 1.77 exhaust vales. It seams like one guy that I talked to that ran a Pontiac told me that you could open them up to 2.20 if you wanted, but Iím not sure if thatís true or not.
