340/416 vs 383 vs 440

Build the small block 416, big power in a small package. You can build a 550hp 416 with 10.5 comp .575 solid roller and 285 cfm heads , if put together right.

If you don't mind less compartment space and weight, build a 431 out of the 383 with the 440 crank, they work real good and will make the same power.
