I would expect with all the limitations you have that power would be low (375'ish) depending on the cam.
TQ should be great though.
I would use comp's new thumpr cam, works very well and it sounds nasty.
Carb I would use would be a 750DP Holley.
I'm a Scat dealer so that is what I use. 9000 series crank, I beam rods and KB IC745 piston.
