Man theres no way those factory springs will work with +.600 lift.I think the yellow ones are the best ones(ls6)but pretty sure they are rated .570.Gonna need an aftermarket spring for that cam.

Yellows are rated to .550 or so, you'll need aftermarket for that lift.

i cant remember .550-.580, but i do know for that cam (.612) definitely go with some aftermarket springs.

on a side note LLC, if the man has cars in the 8s & 9s, i doubt hes dealing with ls6 springs too often

dont have many vids. have a few pics

it runs 9.3 ish on motor and 8.7 on a 200 shot. took the lsx out for now to freshen it, right now im tossing a junk yard build together on a budget. have a few stock cube scores to settle here localy and while im at it im hoping to see how i do with the stock internal nitrous guys.

im about $1,500 into the motor so far and that includes buying it. lol i need a drive shaft and thats about it.









this is the only vid i can find. not great. think it was with a 100 shot. went 9.1 or 9.0










street beater. makes about 500 to the tires
