Re: 1/4 mile times with ls swap

well i got the converter lockup all sorted out. Ended up being a bad connection inside the tcc relay. Replaced it and now it works perfect! also got the rear end built with an auburn diff, 30 spline axles and 3.73 gears. 70 mph im around 2100 rpms just perfect. i average around 19-20 hwy and it pulls great!. Took the truck out to the 1/4 mile this past weekend. Got a best of 12.9 at 104. that was with a 1.9 60 ft. I actually got the better time leaving at idle rather then stalling it up. traction was not an issue as i had 275 60 15 mt pro radials. Not a bad time for a mostly stock ls1, only mods are a baby cam that has 0 chop 214/218 duration, and slightly milled heads. Otherwise bone stock everything else down to the exhaust manifolds, intake manifold, etc...
