Im not sure whether i should post this in the engine department or drag racing but here it goes. I have a 76 Camaro that originally had a 305 in it. The previous owner stuck a 350 in it and made it into a 355. It's a nice little cruiser motor nothing too special. I was on a search for a long time for a 454 Big block and found nothing for awhile and stumbled upon a 396 Big block. So i traded him my 400 small block for his 396 Big block. The big block is #3955272 bored .30 (402 i think) and has heads #3931063 on it right now. I will slowly begin breaking it down and buying parts for it starting tax season. I've been told that the 396 is a turd and will not see mid solid 10s NA and i should get a 454. Well now that i've been told no i do what i naturally do and want to prove them wrong. I also have some LS1 fbody friends, LT1 friends and mustang friends bashing on me for going old school and i want to show them up aswell. I know LT1's and LS1's pretty well im just new to the Big blocks and Gen 1 stuff but im willing to learn. But i want to push that big block i have as close to 600hp as i can. If i get 550 i wont cry im sure 500 is enough to reach 10s. I already know i have to build the trans, rear, and suspension but i wanted to start with the motor. Im looking for a set of aftermarket heads for that motor and oval port seems to be the way to go from chevy performance articles i've read. I was looking at a few Brodix, Dart, and Trickflow heads. AFR is nice but 2K is out of my wallet, those other brands are around the $900 range. So if any guru's wanna help me build this car to achieve 10s? step in and lend a hand. Also this will be more of a race car, this thing will see the street maybe once or twice a week or month depending on how the govt is with gas prices
