OK, so maybe I was wrong! I guess that most of the LS1's I have saw run had atleast 2 0r 3 simple mods, some only free mods, maybe some of them do run a little slower than the average! and I will admitt that I have saw some pretty slow L-98's(350TPI) even though my buddys 89' vete ran a 13.2 @ 102 with a 170,000 miles on his motor! his only mods are: !cats removed, custom x pipe with Flowmaster 2 chamber mufflers, 160 thermostat, MAF screen removed, air foil, and a stock converter (2500) out of a 85 corvette, with 252 gears!! I don't know how some of these cars run so much better than others! but some do!! just like those slow 5.0's and then you'll see some running realy strong! some do and some don't!!!!!
