Your transmission is likely a 904. To get more power I assume you have a 2 barrel. Get you a edelbrock performer and a 4 barrel carb, dual exhaust and some headers will help also. There isn’t a ton of choices on rims for the 5x4 bolt pattern. You can get some crager rims always look nice. The reason for the 1 wheel burnout is you have a non sure grip 7.25 rear end. Cool valiant you have there.
