I see Hughes has a new Whiplash cam for the 360 Magnum. Duration is in the 220's i think, lift over .500". That should about qualify, yes? Spendy though... $400. Compared to their other Magnum sticks anyways.

360 Magnum, RPM Air-Gap, Holley DP, Whiplash cam, long tube headers, 2.5" mandrel exhaust, stick, 3100lb car... Hmmmmm... . . .
