You would want to use a dished piston (64cc heads) or a flat top piston (70+cc heads) to get a street pump gas compatable compression ratio, on a 383 or 406 based SBC build.

Roller cam: To make your corvette more "period correct" consider a mild mechanical street rollercam. More power and rpm potential.
Has the period correct solid lifter sound.
These street rollers are very easy to maintain and are very low noise at idle.
All the most powerfull high perf SBC and BBC's use a factory mechanical lifter cam.

Something relatively mild like 236@.050" on a 112LSA gets it done.
lift can be as high as .580" .600" lift using 1.6 rockers to get max performance on hi flow heads like AFR's

example: comp cams 12-770-8 XR274R-10 (can be custom ground on a wider 112-113 LSA and/or single pattern design to tame the idle a bit more.)
This is just an example but something in this duration group in a solid street roller cam will get 'er done.
