I got something for ya...
If both MoPar 383 engines (B vs RB 383) with otherwise the same parts, who makes more power? Consider the parts used to be only factory parts and we are not chasing power with mondo huge cams and trick parts etc...
Both have the same small valve heads and valves.
Since both breath in the same amount of air and fuel, doesn’t the same amount of air and fuel in a smaller concentrated area have a better chance of pushing the piston downwards in the smaller bore rather than spread out over a larger area?
