    What size is the Holley?
    The hesitation issue can happen with either carb. What size accell pump is in the Holley ? Are you even getting a solid squirt when looking into the carb WITH THE ENGINE OFF !!! and working the throttle ? Could be needing a different profile pump cam. Could be timing.

    not sure on the pump size timing should be ok but haven't used a light yet it revs up fine at idle but once a load is put on it hesitates

    While a knowledgable person can make an Edelbrock work as good as a Holley, my impression has always been that it takes a smaller parts inventory to make a Holley work for competition . . Holley's are a little simpler in their operation, so for the "Physics Impaired" (myself included) they were my racing preference.

    Currently we're using a SV-1 and it's almost "Magic"! Altitude doesn't seem to have much affect on it, at least we haven't noticed any changes in plug color and the A/F meter says everything's right on the nuts . .

    On the other hand, on my Street Rod, I used an Edelbrock 650 on top of my 144S Blower/330 Vortec and it worked pretty darned good. We changed the high speed 4 steps leaner and it worked great . .

    Currently I'm using a 2" throttle body on top of the blower and a '91 GMC HP chip and it does even better . . Smooth, dependable and gets decent mileage . . And still gets on the tire when you mash yer motor . .

    EDELBROCK

    You might want to take a look at the new QUICK FUEL Slayer series carbs. A lot of good features and adjustability. And the price is right. PM me if you want to know more.

    Quickfuel all th way. They have all the Holley bugs worked out of the box, nicer finish and see thru float bowls.

    HR-680 is what I would recommend if your in that 300+HP Range, otherwise the HR-580 would be nice.
