Ok I really dont want to go with the norm comcams. I really would like to find out if ne one has a notable speed shop of something that can custom grind me a cam based on the set up i have. I also would like to no if i would need spring pushrods etc. The truck is a 4.8 08 silverado and i am currently running 100 shot of nitrous and i plan on going to a 125 shot when i intall the cam. I have cai magniflow racing canister pavesetter shorty headers and a tune. Could someone point me out to the correct persons to hook me up with what set up would be the best on this truck!
