360 Duster set-up !!
with the right size slick around 28x10x15 you might see a 12.9. if you want to try for the 11's 750 pro form eldo. Air Gap, 4800 stall, 456 gears around a 31x10.5x15 slick to lawnch it hard, bigger cam .202 intake valves, 1.7/8 headers around 15 inch header extensions for the top end. Good Luck Gary
