Recently purchased a '69 convertible with a stock OHC 6 (non sprint) and the ST300 (2 speed) trans. I'd like to move to a V8 and turbo trans.
I have a lead on '72 400 motor out of a Catalina along with it's TH400 with the long tail shaft. I'm wondering what modifications I would need to make in order to use this combination in the car?
From the factory, did Firebirds with TH400's use the long or short tail shaft?
Should I obtain the drive shaft from the Catalina for possible use? (i assume the spline count is different coming out of the trans between a ST300 and a TH400)
If I could find a TH350 trans, would that be a more direct bolt in?
