What would it take

Just wondering

What would it take for a 300 lb driver and a 71 scamp to run mid to low 12's
using a 360 not a stroker : what needs to be done to engine and tranny,rear etc but keeping it as a weekend driver with full interior carpet etc.
This is just a bucket list question :read2:

I'm 145 lbs. & ran 12.5s in a 71 Swinger, i dropped in a junkyard magnum 360 with stock bottom end, RHS heads, re-ground cam (small), headers, crosswind RPM, 650dp, 11" 2800 stall, 3.73 gears, 27" MT DR, it was basically very mild, i'm guessing the race weight was 3200.
