Ls6 Camshaft Swap

no way with that cam. You need some springs good for up to .620" lift. Double check the new revised 918s, they take more lift than the earlier ones ansd they're still the beehive design.

BTW, thats about the same cam I run and I drive it on the highway all the time with a 3500 stall. Just made a 630 mile round trip to SanAntonio Friday with mine.

You're also running a 408 stroker setup right? You've got 83 more cubes than us 5.3L guys.

You would be one of 2 or 3 to ever do that to my knowledge.

If all you want is a power number then yes, I'd go with a huge cam like that. It's not going to be fast, but it will probably make the power you're looking for.

I assume you plan to go swap the heads and intake right?

Do you have any reason for trying to do all this with a 5.3L? It would be much cheaper to swap to an ls1/lq4/lq9 or bigger.

i will being porting my stock intake mani. or looking into getting a ls6 intake or just uping for the fast 92mm ... but i hear ya bout the amount ill spend on it vs just getting an lq4 which is what i would want to get.. i cant find a stock ls6 cam! lol.. sucks but i cant ... a used at least.. also.. if i port my 5.3 manifold, can i put an ls6 or ls1 ls2 tb on it? or would it even fit? am not sure if they have a better openin the truck one.
