Cam selection for L98 with LT1 intake conversion?
I am doing an LT1 intake conversion to my L98, and I've decided to do a cam at the same time. I was pretty seriously considering the Hotcam because I have the LT4 valve springs and rockers, but recently I have been giving a lot of thought to a cam from Comp Cams XE line. It's P/N CCA-08-502-8, the main specs are:
218/224 @ .050
.528/.537 with the 1.6 LT4 roller rockers I have
112 LS
For reference the Hotcam is:
218/228 @ .050
.525/.525 with the 1.6 LT4 roller rockers
112 LS
The cam's are so close as far as the spec's go, it kind of seems like a wash to me. Right now the car has all the basic bolt on's. Hooker longtube header's, cat back, cut air lid, AIR pump elimnator, and a K&N. I am adding a converted LT1 intake, 1.6 LT4 roller rockers, LT4 valve springs, and a cam. All the parts are sitting in my garage except the cam.
The main attraction to the Hotcam is the price. They go for ~$150 on E-bay or the forums all the time. I also wouldn't have to buy new valve springs. If I get the other grind from Comp Cams, not only is the cam roughly $100 more, I'll need valve springs as well. Do you guys think there would be any appreciable difference in power production between the 2 cam? 300 RWHP is the goal, hopefully I get there.
I am wondering if the specs don't tell the whole story. What do you guys think?
Which cam would you choose and why? Or would you choose another cam all together?
My heads are completely stock, and I have no intention of porting/replacing them anytime soon. Here's some flow numbers from my heads. These numbers are taken from a Chevy High Performance article where they flowed 15 different heads. Basically, take these numbers with a grain of salt:
.100 56/49
.200 120/96
.300 160/123
.400 186/140
.500 196/155
.600 199/159
I burn my own chips, so tuning isn't a problem. If I do get in too deep, I live very close to Alvin of PCMforless.com so I can go to him to rescue me if I need to.
Any advice is appreciated.

just for reference, if you go with the hot cam, get new valve springs from gmpartsdirect.com....they are something like $38 shipped, and for that price why not?
