Test N Tune, what will it run

To run 14.35 with an open 3.23 (I assume street tires) is hooking really well.

That's a pretty strong 340 to be so near "stock." A Holley 3310 on an Air Gap manifold and a 3.90 Sure Grip would drop that thing deep into the 13's I would think.

Good luck!!! And thanks for including us in your test and tune day!!!
