The M1 is very very similar to the original Strip Dominator, the Airgap works best in heavier cars where the fatter midrange power will help it ET, but hte M1 is typically going to produce a bit more power upstairs if you have the head, cam and compression to use it....so it really depends on the combo, gearing and weight. The RPM AG design is really only limited at the higher Revs by the cross-section from the plenums to each of the 2 ports it feeds. I will say that the M1 works really well in combination with with the 2" Super sucker.

I've always considered the M1 and the Victor pretty much a dead-heat (if I had one I wouldn't trade it for another) but the M1/Strip Dom always seemed to have better torque on a high comp motor. i've heard good things about the Super victor, looks like if I was at 390+ cubes and turning 6700+ that'ed be the one to go for.
