    Ya it's cool and u have always posted to on my topics with good info. my main concern at the time was towing capability and not really knowing how this cam would perform in a 4.8. I went throught the comp cams book looking at specs of cams that were as close to what i got and comparing their notes for supporting mods. I dont remember which one it was but it was the closest i could find in duration and lsa and That comp had a starting range of 1800rpm which also lead me to my converter choice of 2800 thinkiing it would give me a 1000 rpm of wiggle room to get te engine into a better range. I tried not to go in that blind and actually spent quit a bit of time reading posts on this forum, and pt forum speaking with comp, rci, and I even tried emailing circle d but never got A reply. most of the forum guys with 4.8 were going the 212/218 low lift route which is a completely different animal then what I picked up and the "ls1 hot cam" has the same duration but less lift. It's a learning experience for sure and as mentioned before i love how the truck sounds with this cam. Iguess I'm just going to start saving for the gears first and start there

    I think that is a good idea. Gears give the best "seat of the pants" gain.

    Do those cam spec books your looking at say if that's the rpm range of a 4.8 vs a 6.0? If not then they arnt as much help. Iv never looked at one. But the same cam in each of those motors will have totally difference power ranges

    The catalog doesn't mention cube size but I do know how lower displacement will raise the range of the cam. It's like My best guess on the stall was about 700 rpm off. Cam is 219/228 and .550/.550 114
