Duane-The reasons my motor has the Ultra 850...Tom Lucas originally put a Quick Fuel carb on it and I hated the red anodizing on it. If you've looked at my pics, you know I'm going for a black and blue, sinister look for the car. The Dart block was painted Navy to match the exterior and the rest of the motor is black and polished aluminum for the most part. Had to spend a few dollars to get a black MSD cap, etc. so when I saw the red QF carb it was an instant turn off that didn't fit with my "vision", lol. They don't make a polish/black one. Tom likes an Annular carb, which the QF is, and was, at least initially, not that excited about the non-annular Holley.

I previously ran a 750 Ultra on the 393 stroker in my Superformance Mk III roadster with good results, suggested it to Tom. He recommended the 850 based on what we had cubic inch, cam and head-wise. I think he was a little, if not a lot, surprised come dyno day when she pulled 611 horses at 6200 and 584 lb. ft. of torque! The original estimate was 575 hp. He claims the Ultra is more of a drag racing carb and still questions it's performance in a road race scenario, the reason he recommends the annular QF.

With the size of the fuel bowls on the Holley, I personally doubt there will be a starvation problem blasting through a twisty mountain road. The annular may atomize a bit better but I don't foresee any regrets with going to the Holley. The polish and black is the right choice aesthetically for me and I couldn't be happier with the power this "little" motor wrings out. Happy motoring.
