radical camshaft / pass emissions ? Hello everyone , I am wondering how radical a camshaft I can install in my 2001 5.3l along with ported exhaust ports and int and exh polished . I will install new lifters and pro stock behives with it . Everything else will remain stock with the exception that I may install shorty headers in the future and still be able to be tuned to pass emissions in Maricopa county , AZ . Thanx for any feedback . chris

get a large traditional split and you'll be fine, i dont have much experience with 5.3s but id think something like 216/224 would work nicely
keeping the stock manifolds may help with emissions and will keep the cam sounding a lot more tame
