Small Block 400ci...or...Big Block 396ci????
Which one would you go with?? Ive got the small block 400 which im planning on building up with aluminum heads(2.08in 1.60ex), 6 inch rods and a roller cam. But... I was just teased on a deal for a 396 big block bored 30 over(which makes it a 402ci) and its all redone pushing 430hp. If I got it, I would probably put aluminum heads on it with big valves and a roller camshaft. It would be pushing well over 500hp, but same with the 400 if I built that. I plan on running a supercharger also. The car is a 69 camaro which orginally had a 396 in it. Im leaning twards the 400 because I figured its lighter, but I don't know much about 396 motors, Are they better than the small block 400? The 400 has a 4.125 bore with a 3.75 stroke. The 396 has a 4.124 bore (thats .30 over) and a 3.76 stroke. Theres not much difference there. Whats the big difference becides big block and small block? Which one would you go with??
