Put a couple of turbos on it and a small block is better than the big block for power and RPMs. Look at the dyno numbers for a turbo charged 350 vs turbo charged 327 or 283. The smaller cubes show better HP.
350=650HP@6500rpm
283=690HP@7000rpm
Saw the twin turbo 350 against big block that shook the ground and the 350 smoked him running 5 second 1/8 8 sec 1/4 170 mph.(set the track record for 1/8th)
