I have stock exhaust manifolds, cats and xpipe with magnaflow mufflers.
Anyone have any idea how this would perform with my car (LT4)?

Jake, that is what I have heard too. I think I will go with this instead of hot cam.

I have never been good and "estimating" what a cam will do by the numbers!

seems a little pricey;
LT4 "hot" cam in an LT4 with stock 1.6 ratio rockers = .525 inch lift at the valve which coincidentally is the max recommended lift for stock LT4 valve springs;
better plan on valve spring and retainer upgrades too. Possible new valve seals. May have to modify valve guide height to accommodate the extra lift and eliminate potential valve seal / retainer interference.
If passing smog tests is an issue, investigate that also.

I think they are similar but from what I can tell it might have a little more low end grunt....wanted to know if anyone had a better feel for it than I. I have heard its a pretty good cam tho.
