I ran one, for all the hype surrounding the cam there are better grinds out there.. That said with at least a true 9.5 C/R a loose convertor, plenty of gear & properly tuned it will run strong.. Or you can cheat, not use as much gear or as loose of a convertor.. Instead throw some Rhoads lifters at it & the cam will Rock & Roll from just off idle to 6,000 easy... When I first put that car together it had 3.91's & a loose no name convertor.. The gears were noisey the first time I drove it & got much worse very quickly... I had no extra cash & a good set of 3.23.. I also had a B&M Holeshot & a brand new set of Rhoades lifters... One night of wrenching & I was ready to go for a drive... It ran way better set up that way than it ever did with the normal setup... Sounded cool too with the lifters clattering like soilds..
