Can anyone estimate my horsepower??

Hey I'm building a new motor for my car, i was wandering if anyone is good at estimating horsepower out of modifications, and if they could take a guess at what mine might be after Im done with it? Well Its a 302 bored over .030 with 165 AFR heads, edelbrock RPM performer intake, 650 duel feed holley 4bbl carb, KB flat top pistons with 2 valve releifs, comp cam 1.7 ratio aluminum roller rocker arms, F303 camshaft, carter high volume fuel pump, miloden windage tray, petronix electronic ignition with flamethrower coil. The lift of the cam with the 1.7 rockers is .544 and durtion is 226/226. LSA 109.

Drivetrain: B&M Torque Master 3000 (3200 rpm stall converter)
C4 Automatic 3 speed transmission with B&M rip shift kit
9" rear with 3:55 gears w/ possi traction

This is being dropped into my 1970 mustang with NO emmissions. Please leave any suggestions or what you think of the setup! All these parts are alreeady bought and the motor is being assembled at the moment. thanks guys.

Thats what i figured. thats still pretty good for the street though. what do you think the engine is producing at flywheel?

oh okay. well thats cool 300 horsepower at the rear wheels is awesome!! i was only making like 200 to the rear with my stock motor with just a 4 barell carb and aluminum intake.
