So I just picked up a Pontiac 400 to build. I've read a lot of people wanting 400-500hp on their builds. I decided to spend the extra money and got a 68 Pontiac 400 with #16 heads. Since I'm starting with a 350hp engine stock, could I just put in a mild cam, long tube headers with a little bit bigger diamter exhaust, and a 750cfm edelbrock, I should be in that mid 400hp range correct? The engine is all stripped down so really I could do whatever. I do need rods and pistons along with other parts as I only have a bare block, bare heads, crank, and intake, but I could probably keep the stock crank instead of using extra cash on a forged one since it should be a decent starting point correct? Not looking to build some untameable monster, just a very strong streetable car as it's going in my 78 Trans Am.
