I know the "5.3 cam" topic has been beat to death, and ive spent the last several hours reading, but still have a few questions.
My truck is a 2004 silverado with the iron block 5.3 (LM7). I have pacesetter longtubes, pacesetter ORY, and single 3" exhaust with a mangnaflow muffler. I have a S&B CAI and I installed LS1 electric fans.
I have a 5" lift with 325/65/18 tires (35x13s) and 4.56 gears. Have also done extensive tuning with Hptuners with my wideband.
My plans for this truck are basically in addition to what ive done, I want to add cam, supercharger, probably trans next and with a 2400 (ish) yank torque converter, then replace the 10bolt with a 14b.
The 4.56s with 35" tires are the biggest I plan on going with ie, no more lift since practicality falls off pretty quick after that.
From what ive read, being a lifted truck and all, high duration is a bad idea. So I was thinking somewhere in the 200-210 range with .55 lift and 112lsa. I dont really care about the sound at idle, I am more concerned with how it performs. The biggest stall I want to go with is 2400rpm, so I am looking at rpm range from 2000-6000, with the emphasis on the low and middle. Although would a SC not pretty much take care of all low-end needs?
Ive seen the Comp XR259 mentioned quite a bit as well as the Comp 218, but wasnt sure how these will work with the blower since I dont want to change cams twice. What is the main difference in a cam for boosted and a cam for N/A?
Any suggestions on specs and/or cams would be great. For springs I was planning on some yellow LS6 spings since I dont think big lift is what I need.
