I ran 13.26 @ 105.2 mph w/ the following mods: catback, midpipe, predator, 4.10 & mac cai. This is less than a bolt-on GT considering the only true mods (midpipe, predator & 4.10).FST FORD said:everyone always says a full bolt-on gt will run a ls1. ive owned both, i dont think so but thats just my opinion. not sure exactly what classifies as a bolt on but if it means t/a, u/d, intake, exhaust [midpipe and c/b no longtubes!], t/b plenum, some minor suspension work? gears maybe, etc the 'smaller' of mods..i dont see how you can hang with even a stock ls1.
This LS1 territory (13.1-13.5 @ 103-106 mph). I don't see why I wouldn't hang with one?
