Ok currently starting on my winter project of building a new motor for my 82

My base for this is a 3970010 4 bolt block
.030 over, with arp studs

going to use a Eagle rotating assembly (pistons +5cc, rods and crank)

cam I'm thinking of using is this a Comp cam nitrous cam specs are
Cam and Lifters, Hydraulic Flat Tappet, Advertised Duration 274/292, Lift .487/.501


as far as heads I am thinking either a set of world, sportsmans II 64cc 200cc intake,or motown 64cc 220cc intake

carb is a speed demon 850, intake is a edelbrock rpm air gap


So all this said what should be my expectations for hp and torque be before subtracting for drivetrain loss (200r4)

I will also be adding somewhere between a 150 to 200 shot of nitrous to this (why I choose the above cam)

All input appreciated

I have a 750 Speed Demon that Demon Carbs says wet flows up to 930cfm.

Carb size = 355(6500)(0.85)/3456 = 568 cfm, where 6500 is rpm, 0.85 is volumetric efficiency. For a 7000 rpm max, plug in 7000 instead of 6500. VE is normally 0.85 for a street engine. I don't know what effect nitrous has on this equation. Nitrous has it's own oxygen, but you still need the fuel to go with it.

Maybe call Demon. They do have a sizing chart on their site.
