SPF 522 has a new KC 427 with ported Air Gap dual plane, 236/242 @ 050 cam, aluminum flywheel. excellent street manners, cruises at 1600 rpm, instant throttle response, and a very broad torque curve... ample power everywhere.

4.10 is a lot, especially with an aluminum flywheel. my motor unwinds quick, shifts need to be very fast or rpm drops too much. Currently have 3.90s and plan on dropping to 3.27


On the diff, solid bushing mounts will take care of wheelhop, a major contributor to broken halfshafts. Purchased them from Craigs Cobras.
