Magnum Camshaft help?

Are you just trying to embarrass someone specific, or is there a time you're looking for? Have you modified your suspension and chassis to effectively get all the time you can out of it? Or are you OK turning your tires into expensive clouds of smoke in pursuit of shaming someone?
It ran mid 12's just fine with the 340 in it. Trans brake, Super stock springs, drag shocks up front, snubber and old M&H Race masters. Probably drag radials this time around. Roll of time slips in the dash as fat as a Lone Star can. I do have a friend that likes his Mustangs ;)
