A 302 bored and stroked to a 347, SVO heads, 355 rearend from a stock 273. Dyno test was 505 HP at 5700

As I said, my Honda S2000 gets 240 horsepower out of 2.0 liters - 1.2 horses per cc - unheard of in a naturally aspirated engine.

Your monster gets 505 horses out of a 5.69 liter engine - .89 horses per cc.

I'll have to check out the torque specs, and get back at you.

Again as another poster stated the cc/hp ratio is not as important as the hp/lb per car. Your car weighs somewhere in the neighborhood of 2500-2600 lbs right? With 240 hp. Vs a 3200 lb car(it was originally around 3400 but like I said I've done a modification or so) with 505 hp. You do the math.

The only way I would be able to get even close to your ratio is adding a charger. Do you really want someone driving down the road next to you with say 650+ hp? And with some of the new chargers ATI is putting out even that number is quite low

And the torque according to Honda tops out at 151 ft/lbs at 7500 RPM
