One for the rich small block guys.

Mopar's one-up on chevy's 1000 hp n/a 632. If I remember right, that's a 40k engine, so both are right around $40/hp.
Unfortunately, I can think of better places to spend $60k, even if I had that much "stupid money".
Besides, about 99.9% of (street)drivers would be stupid dangerous with that kind of power. I know I would.
450 whp got my car in the nines, 1200 whp is insane.
