How much Horse Power and Torque do u think I can safely run on a stock '67 Chevy C-10 frame before I torque it out of alignment. The trucks gonna have an 8point roll bar, and I want the frame still enough to be about to launch with full traction and not worry about bending the frame. By the way, its a 500cid Caddy motor that is making 500hp and 600torque, and future plans call for a 8-71 blower am I gonna need to box the frame. Does anyone have experience boxing a frame like this? How's it done?
