Bought these used off LS1Tech but traded my C6 for a Z06 so can't use them now. SLP says they add 10-12 HP. Adds 10% to lift of cam (for example turns a stock LS6 cam from 0.550 lift to 0.599). Perfect bump for those who don't want do a full cam swap & have to retune ECM. Works with stock valve springs on some truck, Fbody & vette motors. Details from SLP at http://www.slponline.com/view_product.asp?P=50185

New they are $599 + shipping, I'm asking $220 shipped.

 

Did you install them when you had them? If you did how did you like them?

 

Never installed them before I traded the C6 on the C6 Z06.
