Both manifolds require high revs for optimized power, both losing some tq till certain rpms about 4.5k for the cj and 5-5.5k for the boss.

Yes I see what your saying if your not shifting at 7,700 rpms with the CJ your not fully utilizing it and it should be done with the oil gears and valve springs..
