i would suggest checking out this part number in the summit catalog: CCA-K16-233-4
it si a complete kit to install a comp cams high energy grind in your engine. should have good street manners as it is only meant to make power to 5000rpm and is not what i woudl consider a big cam at all, although it is bigger than most of the other selections listed.
one thing to make sure you look into is some tuning. whatever cam you choose will require the computer to be retuned to operate properly and take advantage of any new found power. other things to look into if funds are available woudl be getting some mild head and intake porting done, looking into free flowing/larger exhuast, and finding a less restrictive air intake system.

has anyone ever put an LS1/later 3800 air filter system onto a 3.4 car?
