A833 NP A body trans ID help & intro.

What kind of HP are you talking for there to be weak points? Didn’t really follow your previous reply. Bushings in the counterbores, 307 main case? Like a cast iron one? Forgive my lack of knowledge but definitely want to make sure I do research before buying something. The motor is stock as of now with a mild cam. Plan on building the 340 to 400 hp in the future.
