[Super73]

If your goal is 500hp to the rear wheels, it is going to take a lot of planing. I just looked up that cam and even with awesome flowing heads, I don't see 500rwhp.

Example and I know they are different platforms all together but my combo is:
13-1 compression 418" LS motor
My heads flow 35x cfm on the intake side
I run a Super Vic intake that has been ported to match the transition in to the heads (heads touched up a little as well)
I have a 254/260 hyd cam with .62x/.63x lift
2" headers in to a 3" X-pipe with dual electric cut outs
I run E85

I make 521rwhp through a power glide trans with pretty decent sized converter (5k on the brake and flashes to 4,600 off the 2-step).

Just food for thought.
