Recommended WOT RPM of the 500HP is 4800-5200rpms. The rev limiters are supposed to be at 5350rpm, but vary somewhat and also tachs can be off. If you have TB IV ignition, the rev limiter is a separate part and can't be changed. If its a TB V, then I think you can have the limiter in the ECM changed.

30" Lab finished B1s. However, my 500 HPs are now 600 HPs with AFR heads/custom cams but the rotating assblys are stock. Little higher spring pressure than stock. Using Morel lifters, Ferea valves and Manley-Nextech springs.

My distributors are stock. I went with the Crane HI6M boxes because they are compatible with hall effect trigger sensors that are on the stock distributors. Don't you have to run a mag trigger with the MSD boxes? Running 36 deg total timing with the aluminum heads, 9.6:1 compression (93 Octane for insurance against preignition/detonation).
