Hello i have a 2004 4.8L Silverado so for i have Prodyno cold air intake, JBA Titanium Headers, Magnaflow cats, True dual flowmasters, and Hp Tuner. I am now thinking of turning my engine into an ls6 based engine he what im thinking about doing.

-Swap out my stocks head with ls2 heads(will they fit on my LR4???)
-Swap out my stock intake manifold with an ls6 intake
-Put some Compcam 1.7 rockers and springs with a .600" lift.

Now where i need help what type of camshaft should i get? an ls6 camshaft or a compcam truck performance camshaft? also what size pushrods and lifters should i use with which cam? Thanks for your help

 

just curious but how would those things equal an ls6?

EDIT- You'd still have a 4.8L block

 

After awhile im going to change over the whole lower portion of the engine block, crankshaft, pistions and rods ect.... but thats later

 

why don't you do this?

buy an lq9, put some 243 heads on it and run something like a 224/227 in it. Then you would essentially have an iron block ls2 engine

 

thats a good idea but im not going to change the block for about another year or so, but i can buy those LQ9 blocks off ebay for about 350$-550$
