well i have been trying to decide what cam to install in a 2001 ls1 6speed...it has 410 gears and the reg bolt on with a 90/90 set up with a 125 shoot and stock ls6 heads. the car runs 95% of the time on motor

 

With the gearing you have available you have a great opportunity to run a really healthy camshaft! I'd look to something like the MS4 camshaft. We've seen 450rwhp out of stock ls6 heads & the ms4 camshaft! What kind of power does the car make currently?

 

the car has a custom cam in it that is around a 224 or so... it made around 410 or so on motor but the cam is like 5 years old so it time to move up to something bigger. this numbers was before the intake...i cant recall what it made on bottle since it been a while
