Looking to convert my TH350 over to a 4 or 5 speed. Forets offers a converted 3550 with matching parts. I currently am running a 350 HP '69 Camaro 350 in an NAF Cobra. Any suggestions?
Tremec is coming out or already has out a 3550 and TKO II that bolts up to the Chevrolet. The input length, pilot bushing diameter and bolt pattern are the same. The standard 3550 has a .68 overdrive.
