It's quoted at 660rwhp. Seems bogus, are you sure that isn't with nitrous?

^^ um, look at the sidebar.
For those numbers (660 hp) out of a 4.6-5.2 engine, you will need some form of power adder - not sure if FRM knows that. SHM builds engines for people to use with nitrous or FI, they also build strokers that put out 450 hp and ready for more.
In a displacement-limited situation, DOHC rules, while in a max-horsepower-limited or size-and-weight-restricted situation, OHV tends to be a better choice. It all depends on how much money the competing parties are willing to throw at the problem, however. You can easily build a DOHC 4.6 to make similar power to a much larger displacement stock LS1, for example. It just costs more, and likely will be a little heavier and a lot larger.

Pushrod V8 has a small advantage in front-engine cars.
DOHC V8 is the better choice for mid-engine cars.

I'm sure you can provide some facts or analysis (even just one of your usual magazine quotes) to back this up...
