I monkeyed around with the 440 for the wagon a little bit tonight. Since yesterday was Halloween, the engine decided to dress up as a 351 Cleveland:
:dance:
The funky valve covers, as far as I know, were van-only. There's no oil cap, just the two breather openings and a hole for the PCV valve. Also check out the wacky fuel line. It comes from the pump along the oil pan rail (there are clips down there for it), up the back of the block, and forward to the ThermoQuad. I haven't looked at the front of the engine to see where that steel vacuum line goes yet.
When I removed the carb, the driver's side rear bolt was only finger tight. Once I commenced to removing the plug wires, I came up with a theory as to why this otherwise-nice Class C motorhome got junked. My theory goes like this: the engine developed a valve-cover leak so common to big block Mopars. Dude changed the gaskets and gooped 'em up with silicone to make sure they wouldn't leak again, but in the process of bolting them back down, he pinched the #5 plug wire between the valve cover and the AC compressor base. He just cut the outer silicone jacket on the wire, so it probably ran OK for a while, but then the miss started. He put new plugs in it, which didn't help. He changed the cap and rotor, which are in such nice shape I'd have no problem using them on another engine, meaning they not only didn't fix the miss but it didn't run much after that. Next up, rather than take the obvious route and change the plug wires, he apparently had the carb off. I don't know if it's been opened, but it was definitely off the intake. It was bolted back onto the engine with a new gasket--which he set
right atop the OE gasket, which was still under there tonight. At this point, I imagine it ran even worse, since the carb wasn't even solidly bolted to the engine. He probably got pissed and moved it to the backyard, it sat for a few years, and then he got sick of looking at it and junked it... never once attempting to change the plug wires. In his defense, if you've ever seen the plug wire routing on a big-block van, it's a God-forsaken nightmare. Anyone need 7 good date-coded plug wires?
#5, which is why I believe this thing was junked at this point. Obviously, I have yet to crack open the engine and God knows it could be bad in there.
