yes, holly 5200's were found on Ford Pinto's among others (also vega and a few others). They are a weber carb that weber licensed to holley during those years. They are a 32/36 mm progressive two bbl. They work pretty well on an inline motor, even with an adapter (2 to 1), better without adapters or the above adapter. Not sure of the dimensions, but not the same as any rodchester, or holley 2300 series 2 bbl. I like the 1974 model, threaded fuel inlet as opposed to the earlier pressed in brass nipple inlet. If you use them, make sure you install the carbs so that the main jets are pointed forward. The are installed in a corner of the fuel bowl and will uncover on hard acceleration leading to a big giant bog (ask me how I know, lol)

If you have a really modified motor, then its the DGEV 38 mm two bbl. larger then the 32/36, a little more expensive, and not a progressive carb. Not really adapter friendly because of their size. but runs like heck.
