Look at it in the most simple of terms......

440 vs 383.
Both running 10:1 Cr, ootb rpm heads, rpm intake manifold, 850 carb, 1-7/8” headers, MP 509 cam, same rockers.

Which wins that battle on the dyno and at the track in a 3500lb street/strip car?

68 Satellite, 383 with stock 906’s, 3550lbs, 11.18@123
