If it has the small output shaft, like it would if a slanty-trans, Yur kindof stuck on how much power you can slam thru it. The rear bearing is only a 307, and the U-joint is a 7260. So, all-in-all, that's three strikes for more than a 318 2bbl.
furthermore, If yur thinking of putting it behind a V8, you'll need a different front end on that thing; everything forward of the maincase.
I know your address says South of France, so if that is all you can get, and it's for a slanty A-body, well then, that may be your only choice.
