Where in the 12's you want to run? Top side, 10-10.5:1, xe268H, LD340/RPM/Air Gap, 750dp preferably an HP, iron J/O/U heads with mild clean up, stock/HD rockers, headers, 3500-3800 converter, 4.10-4.30 gears, 28x9 tire.
Make it hook and it will run 104-106 and high 12's.
Want to go faster, put a bigger cam in it and possibly step up the converter and heads.
