Say what you want about automatics. But when that 508 purple stripe cam starts working and that 8-inch turbo action converter hits, those 513s will propell you so hard that you'll have to reach around back of the seat to scratch because your testicles have gone through the crack in it.
I wonder if that's anything like my custom ground 603 lift cam with a act Technologiesw 6 Puck clutch on 9 lb of air in my Hoosier wrinkle walls and I sidestep the clutch at 6 grand?
