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.

thanks, i hope i don't spin too bad, i just put 4 new sensa trac shocks on it, and it made a lot of difference in ride/launch, its a lot softer. then again, i forgot to mention that this truck has a "looser" converter than normal.its just a "one of a kind i guess" i can stop and build it up to 1800 rpm before it starts to move lol. i found that out when playin on the street once, i can build it up to about 1500 punch it and after a few feet of spining it will hit 6k and shift into second, it about half bogs when it hits second while burning the tires, it goes from 6k to about 4k and burns it about 2 truck lenghts after the shift..

so yeah, i hope to have a 3.73 posi in there this winter, i'm tired of getting stuck everywhere, peppy v8 and single trac. sucks lol. tires are 27 in. tall, hey since we are on the subject of formulas, would you happen to know how to calculate tire size to gear ratio? what i mean is i don't know how tall of a tire gear ratio's are based on, or how much 1in. taller or shorter will affect your true ratio. my truck used to have 29 in. tall all season radials, i went with a regular 2wd tire that is 27 in. tall. noticeable difference, truck felt a lil snappier out of the hole. i'm guessing the shorter tire put it closer to a true 3.42.
