A Pro-Form 750 or 800. Or for a little more money the Holley 800 hp.

Re: What size and who's carb should i get

On this type of combination, if it is properly matched, a 750 usually works best. An 850/1000 will make slightly more top end power but usually be somewhat or even terribly rough on the low end and basically just kill low end torque. To be optimized the 850/1000 would need a very loose convertor and a lot of rpm to realize any real potential over the 750. I list the 850/1000 together because a standard Holley 850 and a 1000 HP are actually the same physical size. Be aware that carb cfm ratings are all over the map from manufacturer to manufacturer. Another option if you decide you have to have a 850 is to run one with annular boosters. These help with low speed response and flow slightly more than the 750, but not nearly what the 850/1000 will. Whichever manufacturer you choose be aware a 750 from each manufacturer will be different. The Demon's, and most ported holley's (AED, for example) will flow more air than the stock Holley without losing much, if any torque. Std holley has 1.375 venturi while Demon has 1.4 venturi. Most ported carbs are similiar to Demon. This is the way I would go on your combo.

VERY GOOD ADVICE, BUT THE 750 ISNT ENOUGH AIR(CFM) FOR HIS HEAD COMBO, IT WILL RUN OUT ON HIM..I AGREE THE 850 IS PROBALLY THE BEST CHOICE....

750-850 Holley should be good

Demons flow higher than Holleys of the same size (Demon 750 flows in the 930 range Vs. Holley 700 range)

Same reason I recommended the Pro-form over the Holley the Pro-form 750 race carb is less expensive and flows 830cfm.

Re: What size and who's carb should i get

I am a firm believer in the Q-Jet. A properly tuned and modified Q-Jet can easily support 800+ hp. Just ask the guys running the Nostalgia class and lifting the front end. You get the best of both worlds. Small primaries give great throttle response and MPG while the HUGE secondaries provide GREAT power.
