3:73 or 4:10 with 4000 stall.
But, to answer you rquestion, for MAX 1/8th times, 4.10, hell if 1/8th mile is all you care about ( don't drive the car on the street at all, race only) I'd go 4.56 Ask some of your local racers what they are running for gears in their 1.8th mile cars, it's not uncommon to hear 4.56, 4.88 and even higher
