right and i have no idea on what would be the right one. I want and everyday type cam that im gonna get the most out of. Probably something with low end or mid range. Any ideas?
I talked a while back to Allen about his thoughts on camshafts for our 4.8s. He said the Comp Cams 212/218 .522/.529 114 LSA LS1 camshaft is a pretty good choice. You may be able to get by with the 216/220 .525/.532 114 LSA. That 216 ID is pretty high, so I'd ask around some more before deciding.

Thunder Racing has the "Old Man Truck Cam" 214/220 .600/.525 115+2 LSA. I talked to one of their guys (I think his name was Dave, real nice guy), and he said they have tested this one in a 5.3 daily driver, but not a 4.8. I think the main concern is the lobe separation for this one.

One way or the other, you will need to upgrade your springs. Comp Cams 26918 is a common choice. And if your going to take it that far, upgrading to titanium retainers may not be a bad idea. Upgrading the retainers may be a bit of overkill, but if your going to the effort of doing the cam/spring upgrade, why not spend the $200 extra to beef it up.

Finally, before doing the camshaft, long tube headers are in order. A stall converter will enhance it even more. Plus a Nelson tune (or update).

Good luck.
