Marv Ripes at A-1 is a great guy to work with. I have a local machanic(Dukes Garage & Machine Columbus Oh.) build the trannies to his specs.A-1 Marv Ripes custom builds your converter so you will need to talk directly to him.We also use Crane ignition components their components are very easy on the crank & other engine components ,do to the way they fire the engine during staging & burn out.My dad is a large man 6'3"-345 lbs.so he test the strength of all of the components .He has been very happy with our setup and recomend A-1Mark.B
