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
