RE: 5-speed conversion for 69 Mach 1 428CJ ??
By Cobra428 - 09/13/2005 6:14:01 PM; IP 66.136.159.157
I have a 428CJ in a Cobra kit car. I converted from a top-loader to a Tremec 5 speed. The input shaft has to be cut down on the Tremec (Dark Horse can do this for you) or you have to add an adapter plate. Then the transmission mount has to be moved up and back, or you can fabricate an adapter. Dark Horse may have a different cross member or adapter. The shifter was in a different location than my top loader. There are 2 different 1st gear ratios and 2 different OD ratios. With all the torque of the 428, I'd use the higher first gear. OD depends on the car and how you use it. If it has a radical cam, then I would go with the .83 OD. If you want an easy cruising gear, then use the .68 OD. I have the .83 gear and I love it.
This thread, so far...
