470 vs. 500?

A 373 is a nice idea.
The following is at 1.5 hp per cube.
This is an excellent street strip level that can be driven as a weekend warrior and should still be streetable enough for that once in awhile drive to out door meets & milk runs if need be. It would be my max. Level to push for this particular ride.

A 373 is about 560hp.
A 408 is about 600hp.
A 470 is about 700hp.
A 500 is about 750hp
