Great out of the box carb

Installed on a stock 64 327 Impala SS. The job was very simple. The only issue i had was having to modify gaskets and plate that came in the box. The opening needed to be enlarged slightly. It is not a square opening, it tapers. Not a big deal. Two pumps and fired right up. I did have to make adjustments from being at 5k feet altitude, carb is pre set for sea level it says. Appearance is great it looks pretty cool. Car runs far better than it did, smooth idle and acceleration, cruises nicely not erratic at all. I did order the carb specific fuel line and filter kit from Pure Choice Motorsports and that is well worth it, plus the line to fuel pump kit.

on a daily driver. I could not tell from the product description that the fitting I needed to connect the 3/8 flare fuel line was included, as well as a 3/8 hose barb fitting. So I bought them seperately.

I have a '73 Duster 340 currently using a Holly 700 double pumper with a stock TorqueFlight automatic trans. Not being a racer I've been told that the Holly 700 is too much carb for a non racing car. They suggested the Demon 625, would this be a good fit? And would it improve my gas mileage which currently sucks?

I just purchsed a dual plane intake (91011235). Now I need a carburetor. I am looking at this Demon, but I'm concerned about the butterflies and this new "goggle" design hitting the separate planes of the plenum in the middle of the intake. Will this work, or should I go with a different carburetor instead?

Will this fit on a 1966 Cadillac w/429c.i without making mods? This engine uses a spacer for the crankcase ventilation for the factory Rochester 4-Jet Carb. I need to know what 'Complete' parts I need to complete the install, if this carb will work with my application. Thanks in advance, Joe
