As for detonation tolerance I am running 11.5 with stock ported by me iron magnum heads and a tiny 221@.050 cam 91 octane and ZERO sighns of detonation, try that with some dinosaur open chamber LA heads.




I would sure like to see proof of this but I never see any FAST magnum small blocks out there.
