they are not priced to to bad, a out of the box hp 950 is 650, i got a hp1000 reworked, blueprinted, dominator metering for my 496 for 780, that extra 100 bucks is well worth it, especially the tech support he gives.

I had a demon on my vette and it was junk,I may have just got a bad one or a fluk misfit,and the only parts to fit a demon are demon's,nothing from holley fit's.If you find one of the old gold claw series carb's they were awesome,to bad BG bought them out,to corner the market with there junk.
