65 cuda help

My first project would be brakes. single pot 9" drums are terrible. 2nd would be a front sway bar. 3rd would be to get mid 3 gears for your diff or upgrade the diff entirely to a 8.25-8.75 with some 3.55-3.73 gears. The solid cam 273 loves to rev. Keep factory exhaust up to 250 HP, past that they will hurt you.
