SBM "MagnaVelocity" mushroom camshaft.

Well, Schneider "says" they have a "Mini Express" mushroom cam for a small block. BUT reading between the lines I THINK what they mean is they have a .903 lifter diameter "equivalent" camshaft, because they list shroom lifters nowhere. You might try calling them and see what they say if you have not already, @Bighead440 .
