500rwhp with Radix supporting gear considerations....

Of course this is just me, but with the limited amount of boost the Radix can push out to a large C.I. motor, there really isn't a huge need to drop the CR that much. I don't see you needing 9:1 CR with only 8psi of boost.
If you think you'll have much more that 8psi after heads, headers, 3" exhaust, and that large cam, I doubt it. That doesn't mean it will be any less powerful, just that its more efficient in getting air in and out, making more power on 8psi.

Be sure to put a smaller pulley on your list of things to get. With those heads,cam and exhaust you will loose a good bit of boost. Thats what is great about making it more effecient, you can cram even more air in there and make mo power 
Example-my 6.0 with cam(smaller than yours), head work,and very freee flowing exhaust. I was able to make 10psi boost on a stock 6.0. It dropped to
6.5-7 with the new setup. I'm now back up to 10psi with my new pulley.
I'm also at 9:1 CR.

You can bet that if whipple ever does come out with an intercooled system, it will be an expensive conversion. I'd put money down that KB would be the first released, but I doubt that it would directly bolt in with a whipple.

Why up the injector size? I though 42pounders could support 500rwhp no problem??
If not, then I may need to start thinking about the future of my injectors, i hope I can break 500 with my setup, but who knows what this pos Whipple will end up doing
