LS1 to LS6 cam install
Swapped out the cam, valve springs and pushrods etc. on a friends 03 Z06. Car went off to get professionally tuned and I ended up with the old parts. The Z06 had about 18,000 miles on it, cam looks perfect. I have an 02 Coupe all stock except for Air filter and mufflers. You know what I’m thinking. Will the LS6 cam work OK in my car with the stock tune? I have read several places including Thunder Racings website that the LS6 cam has a .050 smaller base circle. Guess I could measure the cams when I have them out but looks like I would have to get some longer pushrods. Other than that it would just be gaskets, crank bolt and my time. I know without the LS6 heads etc. I would not get 400 at the crank but still might be worth 25 or so HP? Wada ya think?

When I was in that position I sold that cam and bought a used GT2+4. I got it straight from LPE for $200. The LS6 springs will work with this cam. Your cam is worth $150, maybe a couple bucks more. If you can find a similar deal (Call LPE or do a WTB on LS1tech.com) you can have more HP for about $50.
Edit- I'm pretty sure that you're going to need longer push rods with that cam. The Z06s have longer valves to make up for that smaller base circle.
