Progressive 2bbl

Thanks for the hint on AMC, Chief. Went digging around and found 2 progressive 2bbls they used from the mid to late 70s. With AMC I6 CID close to Mopar, these are likely set up adequately for the 225 /6. The carbs are the Holley 5210 and the Motocraft 5200.

The Motorcraft comes with a caveat. All threads are metric. The early bolt heads were also metric. Later bolt heads used SAE sizing.

Thanks guys. Now I start collecting parts.
