I do Have a email into cam motion about what they recommend for me, waiting to hear back from them. I also did notice last night that in their section about there cores they do say the 8620 is standard core. I just assumed it was the other way based on the cams i looked at give you all three options but defaulting to the cheapest core, my apologizes there, i wasn't trying to argue so i'm sorry if it came off that way. as for being cheap that is correct. haha I grew up poor and straight out of high school landed a job in a body shop doing restorations making what was good money for a 18yr old kid. I blew every penny of it and after i left there had some hard times for a few years. Now im 27 with a wife and family, a good job as the diesel tech at a gm dealership and have a SMALL "business" working on go fast stuff when i can here and there. I don't like spending money, unless its on my z28. I know better than to be cheap but i just cant help my self at times. As much as i love my suburban i have a hard time wanting to put a $450 cam in it. Especially when i want to get it on the road asap and tuned so i can start saving for the blower. Just a insight to my mind for eveyone 
This difference in the price of the 8660 is due to the cost of materials, The difference in the price of the 8620 is the expense of the hardening process. We make about the same amount on all 3 alloys, so there is no profit motive to suggesting one over another.

Bob at cam motion recommended their 212/228 .553 lift 115lsa blower cam. Bob told me it won't have that idle i'm looking for but it will perform how i want. ordered some parts last night and saving up now to get the cam coming. once i get all the parts ill get a build thread going in the conversions section. thanks for every bodies help!

I had a Lunati 212/218 113+4 ..530 lift in my 5.3 and that cam ran great and you could tell it had a cam at idle. I have a 222/226 115+3 .600 lift now and if i wasn't building a 6.0 for my truck i would swap the 212/218 back in. I don't have any dyno #'s for either but the 212/218 felt better everywhere. I also have TSP 5.3 heads with 58cc chambers with both setups.

VS-2257 Valve Springs? has anyone used the VS-2257 valve springs that are included in the CS-MTC-8 cam kit? they're spec'd at 95#@1.800" 300#@1.200":

do you think they would be adequate for .585 lift?

212/218 550/550 with ls6 springs I have a new in box cam
4.8 swapping my 99 k2500 suburban and wanted to do a can upgrade while I was at it. This cam is priced well and looks promising. Advertises a operation range of 1500-5000rpm. It says its for the 4.8 but I know the stock 4.8 cam makes power to about 52-5500rpm. I don't want to sell the 4.8 short in rpm. I do have a 4:10 gear and she runs about 3000 at 75mph. Specs say 212/218 and .522/.529. Didn't know if anyone had experience with this can or not. Thanks in advance.
