Heres another response to the above, I'm still unsure? whats your take?
This camshaft is used in forced induction applications. As far as lift, not as much is needed for forced induction applications. Keep in mind, the more lift and more duration in a camshaft nets more mixture in normally aspirated engines in which you rely on vacuum to fill the cylinders. In order to get the most possible mixture in a NA engine, for more power you need more lift and duration. In a forced induction, you won't have to go to that extreme, therefore a little more lift in a forced induction won't make as much difference, as it would in an NA engine. Going to a 1.85 rocker is only going to add more lift which you probably won't notice a whole lot with your supercharger. The GT-7 camshaft reflects a good exhaust system as well. If you have a stock exhaust, you may want to consider the GT2-3 camshaft.

I agree with much of what this person said, like the lift part. Since you will have a blower, you won't need .590-.600 lift that N/A guys will require to ge the big numbers you will easily get with the Radix....you can get the same results with .540-.560 lift. This is nice, because then you can go with the Comp 918's instead of dual springs.
As far as rockers, I'd stay with the stock ones and just get any lift you need ground into the cam. Why change two components (cam+rockers) when you only need to change one (cam)? I haven't heard any really good stories from people using aftermarket rockers.
As far as that crazy exhaust duration and 121 ICL, I have no idea. What is the LSA? If it's 116, then the cam is ground 5* degrees retarded...I don't think ICL tells the whole story, you need the LSA as well.

Also, what the need of a 22* exhaust bias is.
I'd be very interested.

I would like to know too. Who the hell makes this cam anyway?
