will my th350 transmission hold up with aluminum heads and supercharger?
I have been debating about adding aluminum heads to my car but I wanted to know if the rest of my drive train can handle more power.
I currently have a stock 76 camaro 350sbc long block with a 142 supercharger installed. The transmission is a stock th350 from the same 76 camaro. and the rear is the stock rear end under my thirdgen.
I figure I can't be pushing more than 300hp with the current smog heads
if I change to aluminum heads will I need to upgrade my transmission and rear end?
I autocross the car and drive it on the street so not drag launching it.
any budget advice would be helpful

without gobs of traction, the axle will live for a while. People ORR the stock 10 bolts with a lot more power that you have and dont usually trash the rear too often.
As for the trans, its old and wont last much longer. Time to rebuild it and upgrade.

It only has 60k miles on it. Does it still need a rebuild (will that make it live better behind the new power level?) What should I upgrade?

Get you a Transgo kit and a 35,000 GVW trans cooler and you should be fine. For better peice of mind get a rebuilding kit with the red frictions and kolene steels then a 36 element sprag and you would be good for 600 hp. After that get you a th400. imo
