non mopar, what do you think my truck will run?

I'll take a wild guess, not knowing how tall you rear tires are, and say 9.85-9.90. Used some qtr. mile formulas with hp and weight, then converted to 1/8th mile. If your close to peak rpm at the stripe, which i assume will be in 2nd gear, and you don't spin too bad, you may get a little more out of it........Best thing is be safe and have fun:D.
