99 ls1 long block,milled 853's,216/220 comp cam,CAI,1 3/4 headers,ported tb,tuned by Alvin @ Pcmforless..

4wd,255/75/17 bfg mt's,3.73 gears and was run in 2nd gear with the converter locked..
Were still working on the tune so there is a little more in it

 

Getting better! Going to up grade the gears?

 

Thanks man

Im not sure yet....The next set of tires will be 265/70's so there a littler shorter than these now...
Id like to go with 4.30's but if i spray it ill just keep the 3.73's

 

Nice numbers and nice truck

 

looks pretty stout!

 

Yeah im real happy with the tq curve so far

 

Run it in 3rd you weiner...

I'd go with the 4.30s either way, with or without nitrous

 

Eh ill do half a run in 3rd next time but i aint take it all the way


I spray it before gears and or run a shorter tire

 

What did you put down?

 

Well the graph says 344/338............................................... .......
