    Does anyone here run a Holley 500 2bbl? How do you like it? How is the performance? How is the off-road ability of the carb on inclines, etc...?

    I hear that these carbs are awesome on trucks and I recently got one for free... trying to figure out if it is worth my time to try and swap it on my truck so see how she works!!

    I knew quite a few guys in Northern CA who ran them on their 390 Fords. They were all very happy with everything but the gas mileage. One trick I learned from them; The vent tube on a Holley is where the gas dumps out on a steep incline, so these guys would put about 2 ft of gas line over the vent tube and curl it up inside the air cleaner-kept em from flooding out.

    ... that is what this came off of was a Ford 390. I was thinking if it doesn't work out on the Jimmy then I might try putting it on the 390 in my tow rig...

    I used to have a 4WD Dodge van that had a big 2-barrel carb sitting on the 360. On long inclines it required that I stand in the throttle enough that manifold vaccum would go away long enough that the a/c controls would lose vacuum. The a/c would start blowing out the heater vents. :( It also got 6, yes SIX mpg.

    When I swapped on an Edelbrock Performer intake and a Holley 600 CFM 4-barrel, mileage jumped to 11.5 MPG and the a/c worked right once again. :cool1:
