We tested a victor against an m1 intake on a 408 with trickflow heads that was making 527hp. The victor had been mildly ported by the late Larry Smith (intake runner work/plenum blending) and the m1 was untouched. We were surprised they were within a few hp of each other with near identical power curves and peak hp at 6,100. From the testing I have seen the strip dominator and m1 are very close power wise.
