whats the max lift for ls6 springs?????

 

ive heard .550 mentioned once

 

someone here has to know for sure.

 

Lingenfelter sells them in a kit with their GT2-3 cam which is .570ish lift.

 

supposed to be .570 lift

 

thanks for the help

 

i think im just going to go with the 918s

 

The ramp speed of the lobes has to be factored in when chosing LS6 springs also. As mentioned, Lingenfelter uses them with cams close to .580 lift, but I believe those cams have "lazy" lobes. On cams with agressive ramps (like Comp XER lobes and Thunder Racing Cams), you want that extra seat pressure to keep the lifters from jumping off the lobe as it spins...so I have read both here and at LS1Tech.

 

so, 918s will be good?????

 

What cam are you going with?
