406 sbc vs 383.

The 427 cubic-inch big-block is an iconic engine. The big-block guys will say that the small-block weighs less, and therefore should have an advantage.

The small-block guys will come in and ...The minimum acceptable clearance is 0.060 - .080-inch between all moving parts and the block.

my experience with sbc vs bbc. when mildly modified, if you have say a 400" sbc (406-434) and a 400" bbc (396-427) If both engines make the same amount of hp, say a 500 hp 434 sbc and a 500 hp 427, the small block will build more torque than the big block. that contradicts most all beliefs about sbc vs bbc.I have a 7500 rpm 383 ci and now I also have a 7000 rpm 427 ci small block.
