Ultimately the gains depend on head and cam selection.

Your picking up 37 extra cubes I would hope to see 1hp gain per cube at the very least and if you figure on 1.5 your talking 55.5

But it comes down to intake heads cam exhaust. Eliminate restrictions and you gain the most obviously. 450-600 all depends on how its setup

383s happen because people have LS1/5.3 blocks to work with, said Capt. Obvious.

4.0 crank is fine. Wont have any issues with pistons especially with modern piston designs.
