I'm running the 02+ oem ls6 springs on my engine for about 1 1/2yr. .540/.541 216/222@500.

I wouldnt go over .550 with those springs.

Where you buying from?

btw...I'm running them on a 3.8 v6

summit, they say they are rated at .570 and a f cam w 1.72s is like .550.4 so i should be fine... i hope

26915 or 26918 comp springs? The ones i got are from legenfelter and are oem takeoffs from an 02+ ls6.

Didnt know summit carried them as well. I'm doing the comp 26915's and going with a bigger cam myself....somewhere around .580 230/240 @.500 114*

Springs are never good to X amount of lift. What's crazy is if you call a manufacturer like TFS that makes cams, and heads, and sell heads with springs, they will tell you the same thing. Always, always, always, call the cam manufacturer and ask them if the springs are acceptable for the cam.

NAL-12499224 those are the springs. and yea this is more of a budget build with spare parts for now im just saying what they are "said" to handle. either way it will work or it wont only one sure way to find out.

I agree. the spring pressures are what are important...
