Hello Group:

Thought I would run this by the experts here. Based upon the below, what's your estimate of HP on my almost finished 496 stroker?

I have a longblock built:
Gen IV Block
GM Alum Heads,118 cc Chambers, 300cc Intake Runner, 110cc Exhaust Runner, 2.25" Intake, 1.88" Exhaust
Comp Pro Magnum Roller Rockers
Cam is hydraulic 292 advertised duration, or [email protected]", .544" lift, 112 degree lobe centers/Hyd lifters
Flat top pistons/9.1 Comp
Dart intake
Dooley 10qt pan/mellings pump

I am finishing the motor with:
Mighty Demon 850 Carb
Thunderbolt IV Dist/Crane HI-6 Box
3” Oil/Power steering cooler
Holley Mech Fuel Pump/Reg
Thermostat Crossover
Lightning Headers

So whaddya guys think?

3 Million Horsepower...

Just kidding, I don't know I write checks for my horsepower.

Somewhere in the 500hp range would be my guess.

Thats a big carb you got there....

Rule of Thumb: 1hp per 1 cubic inch. So say your at 496 h.p. to start. The heads will give a little, the exhaust will give a little, Cam doesn't hurt anything. My guess 530 to 540hp.

Thanks guys.....the Desktop Dyno is saying 530 at 6K, 550 at 6500.

Before I order my carb - you think it's too big?
