A 350, 355, 383, or a 400. Should I build a high reving 355. I saw a article about a 400 bored over, 327 or 350 rods, and custom pistons that made above 400 hp & torque on the dyno. Or, should I go for cubic inches and build the 400 small block, with the ever popular controversy of the over-heating problem.

If you leave the cam the same, you will see very little gain in HP, but it will make peak TQ and HP sooner (about 200rpm).

As for the 396.The heads/intake can only flow so much, and a 383 will peak out sooner. Bigger engines will make more power as long as the top end can flow enough air to feed them.
