Any thoughts about what ppm of zinc I should use for my Mini-Express mushroom setup? I broke it in with 8 qts of straight 30 oil + a bottle of "real" ZDDP and it seems to have survived.
Springs are about 430 lb over the nose. The 1.00" lifter foot is larger than stock, but the cam lobes are actually narrower than a .904 cam (so they don't hit the adjacent lifter). So is that more pressure per unit area, less, or the same? :realcrazy:
Wow! It’s been a while since I’ve even heard of the “Minnie Express “ package... I would imagine full contact pattern with that much over the nose pressure. If you don’t mind, what are the timing events and lift on that deal?
