You didn't mention what you want to use this for, what compression ratio, what cylinder heads, what trans, what gear. Driving a car on the street with 11:1 pistons is cool in my book, but then again $3.00 plus per gallon of gas can get into your wallet big time! Ls6 and ls7 are super motors, but I would have to think that there are much better cams designs available today than were twenty years ago when those motors were new. I called Crane and used their recommendation on my 454 and am very happy!
