13 sec. 360 for $3,000?
My bone stock 72 340 Duster with g 70 14’s and 2.02 J heads, thermoquad,a 727 /what ever stock stall torque converter and 3:23 gears in a 8.75 rear would run 14:10-13:90 @ sea level.
I added some Headers, 2.5 exhaust and H 60 14 Goodyears which got me into got me to 13:60-13:40. It should be easy to get to where you want.. I agree with the magnum short block and heads because they will bump compression and the magnum has roller cam.
I lost most of my times at the light or in the 60ft..
