Rob, Nice build. Just for comparison I built a similar engine for my Challenger about 2 years ago. Just like you I wanted something with a fair amount of torque and was not worried about all out HP as I have power brakes and run the A/C in the summer. It idle's good at 800 and has 13" of Vacuum. It is close to yours power wise.
