The cam you are talking about using is puny in comparison to the ones that have come out in the last year-2 years, and you will not have any vacuum problems. Its likely that you won't need to do anything but drill the throttlebody.

This is the cam I like and plan to get.

98-02 LS1 CC-custom4 Up to 400RWHP is obtainable with this fast ramp cam with bolt ons, STOCK heads, and dynotuning in an M6 car Lift: .581/.581 Dur@.050: 224/224 LSA: 112 114

That BTW is off of speed incs web site as one of the cams they sell. The 224/224 is a great compromise cam IMO. With a good tune it's still emmissions passable, makes good power and maintains fairly decent street manners for daily drivers.

So I say go with a 224/224 114 and mix that cam with a good tune and 3800-4000 stall torque converter. If you want to keep good street manners then get a Yank SS3800 to compliment that cam. Just don't go less then a 3500 stall or you will regret it.

Good Luck

 

That's a relatively small cam, barely bigger than the LS6 (204/218 .551/.547 117LSA), although a 114LSA would give you better idle and emissions, if you have to pass that. You will lose a little low end torque but gain in the mid and hi end.

 

FWIW: I'm running the cam in my sig.

236/239 .601/.610 111lsa

Stock heads.. all boltons sept electric water pump and fast intake.
