Doing some more research, I’ve identified two key components of the engine.
The carb is a Holley 2300 with a manual choke, sitting under a gloopy oil bath air filter. A manual choke! I was half-shocked to find this, but I continually have to remember this thing is from 1964 and I’m actually lucky it doesn’t have a magneto instead of a generator. The carb is crusty and covered in mud dauber nests, but complete. I wonder which control on the dash feeds to the choke? I’ll bet a couple of dollars that’s one reason she didn’t start when we tried it. An inexpensive rebuild kit is sitting in the Rock Auto basket, along with new Autolite 85’s and wires.
The mystery distributor is a Delco cast iron body unit, according to Mike Mayben over at the IHPA forums. In his words, “I personally think that these distributors were the best units used, extremely durable as compared to a Holley.” Well, that’s good to hear. Where I can find parts for this remains to be seen; I think I’ll test it first for spark before throwing parts at it.
I got in touch with the owner of the blue truck with the gas tank in back and asked him if he was interested in parting it out (it’s been up since October and he’s dropped the price once). I inquired about the big stuff—the windshield, doors, power steering unit, and bench seat, as well as the gas tank. He’s still got it and gave me a price for the tank but doesn’t want to part the truck. I looked back at the video I shot, and reviewing the footage I notice it’s not in the perfect shape I remember it being. New poly tanks are $~350. I figure five hours in the car to save $250 probably isn’t worth it unless I can grab a bunch of other stuff, so I think I’ll pass.
