The cam from the 4.8 setup is for sale. I'm not sure of the exact mileage, but I put just at 10K on it. This cam gave me 30rwhp increase in a 4.8 with few bolt ons (e-fans, CAI, HPPIII) at 5800rpm.
Pulls hard up top, left a little to be desired on the bottom end. Would work great with a nice converter.
$250 + shipping.
