69 barracuda stock 318

Im trying to figure out how to turn my 318stock 69 barracuda run in the 11's 1/4 Mile without change the motor on a budget.

Stock 318
727 trans
dana 60 rear 354 gears

The first problem is budget. What is your budget?

Otherwise, start with a super charger and well ported 360 heads/Edelbrock heads and add at least the MoPar 296 duration cam with 1.6 or better rockers.
Add proper stall converter to match the blown engine and cam with the rear gears and cars weight.

Enjoy.
