Any C5 cam recommendations?
 

I have a 2000 C5 with SLP ls1 style cylinder heads, and I currently have a comp 228/228 cam with .571 lift and 112 degree seperation. The combination gives descent high rpm power after 3900 rpm and I had the setup dyno 353hp to the rear wheels. I do have stock exaust system and plan to instal LG long tubes very soon. Can I get more power from a bigger cam and if so, what cam do you guys recommend. I want more power preferably in the lower rpm range. I plan on driving this car daily.

you should have done your exhaust before doing your cam.. Get re-tuned after the exhaust .. don't be suprised if you get an extra 25-40RWHP ..

the headers are going to help you with some lower rpm power. but, ls1's arent made to make extreme power down low. if you want power down low
....go for nitrous. its hard to make a really fast daily driver without sacrificing down low power. you could always go with a bigger stall converter

I'll have my car re-tuned after I install the longtube headers. Do you think my current cam is alright to handle some spray? If so how much do you recommend or don't recommend?

Your cam is larger than my 224/224 which put down 413 rwhp. The headers along with a good dynotune will wake up your car.
