Yep still stock heads/cam but i have 1.6 rocker arms so brings the cam lift up abit. but basically rocker arms are bolt ons and to be honest, they may not have given me much performance. hard to say since i cant compare previous times to this run since the weather was so different
There have been bone stock LS1’s hitting 12’s on street tires i hear. but it doesnt take much for them to go 12’s at all. just stall and slicks will bring a stocker mid high 12’s or better.
I’m squeezing as much performance as i can out of this car. there isnt much left in it now if anything at all! LT1’s/Ls1’s with same mods as me should be mid lower 12’s. Sam’s LT1 went 12.96 at 106 the day i went 13.24… his car is on street tires with stock auto trans and has less bolt ons than me. if he gets slicks/stall, he’ll be mid 12’s EASY in good air like this sunday
