74 T/A 455 crank drilled for pilot bushing?
« on: November 22, 2018, 03:38:24 PM »
Does anyone know if the 455 used in the 74 Trans Am was drilled for a pilot bushing?  I'm considering converting my 74 455 T/A to a manual trans and since all 74 455 T/A's were automatics I'm wondering if the cranks were drilled?

I believe they are all drilled for the bushing/bearing. I use the bearing in mine.

Great, thanks! I bought an American Drivetrain TKO 500 conversion kit and originally planned to put it in my Formula but I think I'll put it in the Trans Am instead.

I believe your crank will be ready for the pilot bearing, I have a 1975 T/A 455, from an auto car, and it is machined for the bearing-
