Need help choosing a converter

Just whatever you do don't get a tci!! Go with a turbo action, dynamic, FTI or Ultimate. PTC can be a cheaper but still good choice for converter! Cope racing transmission carries those!
Dynamic, Ultimate and PTC all have excellent reputations. I had my converter redone by Pro Torque. Drives like a normal car but will allow the engine to do what is needed when it needs to be done. M cam is a little smaller than yours w/3.55’s in a 26 inch tire.

It did cost a few bucks though!
And I’d do it again in a heart beat right quick!
