sportsman's advice

That fish with a good running 360 and 3.55 gears should be in the mid 8's easily. 255/60-15 street tires should be all you need for traction. No need to run higher than premium gas with the stock motor. My fish ran 7.80s with a 360 / 3.91 gears on 255-14 drag radials back when the PO had it. The 340 he put in slowed it down. My car runs a lot faster now with the stroker even though the holley pump is pushing the fuel through the stock small line - that gets fixed this weekend.

The juice will possibly hurt you as it gets more difficult to launch and control.
