VERY easily. You have to think about air velocity and what rpm range your engine is going to operate at.

For SBC rule of thumb is

cubes x 50% = intake port cc, street car

cubes x 55+% = intake port cc, race territory

Valves cannot be too large if blended and unshrouded correctly

another thing to keep in mind is to "match your components".

For example, my boss has a 68 Impala coupe. The fender says 307 but the guy be bought it from says it's a 400. It looks like a sbc so I dunno.

Stock exhaust manifolds, Edelbrock Victor Jr (single plane) intake, Edelbrock carb, stock everyting else, besides pointy "bullet" lock buttons and some 1980s-ish wheels (chrome with a lot of little holes in a circle, they look like they belong on a camper or something).

Yea, it's really mismatched. The car would do a lot better with a dual plane intake, headers, and a mild cam.
