Just wondering.... why are you going to spend the money on a forged short block and stop at a 306? If you are going to drop the money for a forged rotating assembly why not go with a 331 or 347? I think your combo would run better that way. I also think you have too much duration on you cam for a 306 unless its a track only car. You did not say what the LSA of the cam is, but I would guess low 11's on the motor with say 4.56 gears turning it to 7500 or so.
depends on the weight of the car and suspension/tires.
 
I think with the 306 combo you should get the 400hp mark in the RPM you are wanting. Bit I have to agree with Redrooster, why not go with a 331 or 347 with the same compression and have the torque to get you moving and then let the HP run the numbers you want.

Remember though, it's not all about HP to run good numbers, suspension has allot to do with with it also. I would say with a 331/347 with your combo above and decent suspension(traction:nice: ), you should be able to put out some decent times.
 
I'd get 30/36s. 24s ARE too small for a 7500rpm engine with a Vic. JR head/intake. You're gonna need some 4.10/4.30s for that, too. Low-end is going to suck balls. Hope it's track only.
