CB-
I think you will be pretty happy with that motor- it sounds like a good solid street motor with more than enough hp/torque to scare the crap out of you.
But I would highly suggest that you ditch the holley 3310. I was always a believer in vacuum secondary carbs (and still am for other applications) and I had that same carb on my motor originally and I never could get it to run right. I changed the springs in the secondaries, changed the cams on the accelerator pump, changed primary jets, changed the sizes of the discharge nozzle, etc., and no matter what I did it just wouldn't run right.
Eventually I bought a mighty demon 750 (I also bought it from Don at 4seconds flat and would recommend him in a heartbeat) and the car ran infinitely better right out of the box. I was pleased.
Later, I put it on a chassis dyno and, by playing with the timing a little bit and changing the jets, I picked up 43 hp and 21 ft/lbs of torque at the rear wheels. Driving back from the dyno the car ran noticeably better.
To make a long story short, ditch the 3310, get the demon and once the motor is broken in, get it tuned on a chassis dyno and I am sure you will be very happy with that motor. (That is until you decide you want webers, EFI or something else
)
