i bought an alcoa intake/head setup one time MANY years ago that had two - one barrel carbs and linkage.
it was SUPER grubby, and the carbs were frozen up, plus, neither the guy that had it nor i, knew what it fit.
i paid a whopping $7.50 for it, haggling with the guy for a while. brought it home, cleaned it up, got the carbs freed up, and hung it from the rafters in the garage. it has been there ever since.
LOTS of years past, and finally, an article in Car Craft magazine reveled what this was !
it turns out this was a Rambler head/intake, using two stock Rambler carbs ! who would have thought !
i need to get a couple of cheapo chrome exhaust turndowns to use as stacks.
