How much weight is .125 larger bore going to add? And over share will make it rev faster, but all things being equal, 20 more cubic inches add 5%more power

Seriously? Same crank. Wider bore. There is a common knowledge, the claim that having something one off is better, the misconception that everybody knows, that a 383 is a torque monster. Having the same stroke as a 400, all things are similar if you were to install (if possible) smaller cylinders. A bigger bore makes more torque because you have a larger piston area, therefore the same psi pushing down has a larger area to push down on.
Kinda why all old hoteods have/ had 350 Chevys. Everybody thinks its the coolest. So take one, make it bigger, into a 383. Still a boring SBC.
