LS6 springs can be used but I would advise shimming them to within .060" of coilbind for added seat and open pressure. Don't just throw them in and drive.

I ran Patriot Golds on my TR224 and after almost 20K miles they had lost very little open and closed psi vs a set of 918's that were down 20-25psi after 10K miles.

 

Yes it is. I sent him a pm this morning. I tried to look at his dyno graph but a blank page comes up.

 

My dyno graph isn't coming up? I'll have to work on that. Yes, I am running the Comp XR275HR. For now just click where it says pictures in my sig. You'll see my dyno sheet.

 

I'll have to try it at home it wont pull up at work. Thanks

 

They may work but they will be on the ragged edge of their capability. I went with Pac 1518's.

 

i like running the comp 918's over the LS6 springs. these aftermarket cams are much more aggressive than a factory LS6 cam there for use a more aggressive spring to control the valve harmonics better. just my .02
