LS3 Mod ?????

Can someone give me advice??? The only mods I plan on doin are CAI,Longtubes,Exhaust,Intake, and maybe cam. I want to increase the hp with out loosing mpg. What is the best cam for ls3 that gives good HP and minimal loss in mpg, as well as being able to hear it? Also about how much hp would you gain with just those mods?



hope i stuck this in the right place

The GMPP HOT cam is about the mildest cam you'll find. Search the vette forums and you'll find some people that have put it in their LS2/LS3 vettes. 50 hp, no loss of vacuum, doesn't lope, drives like stock, doesn't require new springs, and most see about -1 mpg on the highway.

Overall, that shouldn't hurt you're mileage any and probably give you around 500 at the crank

get a new intake manifold. If you want huge N/A power gaines get new valve springs and cylinder heads
