I wasn't even aware they put Cleveland's in the Econoline Vans. Unless it was some special order arrangement.
It is a more powerful motor than the Windsor which is a good solid service motor. I've been around many of these coming from a Ford family.
This E 350 of mine is one sweet running outfit. It has some years on it but the miles are quite low. It was more of a special needs vehicle and didn't get that much use. I haven't put that much mileage on it myself.
Always prepping for the day though.
Possibly the easiest way to tell the Cleveland from the Windsor is a quick look at the spark plugs.
Those plugs used in the Cleveland are very narrow. The Windsor uses a more standard size appearing
spark plug.
Small plug used in a Cleveland Engine
Plug similar in size to that used in a Windsor engine. (notice gasket on bottom of plug...is probably GM)
When I first purchased my E 350 Econoline I went all over the ignition system replacing the rotor, distributor cap, plug wires and plugs. Took some time to do it and without a wide selection of tools I wouldn't have been able to replace a few of the plugs. Large as the Van is......getting to those parts in the engine compartment is tight.
The best thing I've done to mine so far is install an external lift pump at the fuel tank. When idling I can hear it rattle and banging but that stops when I start moving. The factory lift pump in the tank is worthless in my
experience. I've replaced a couple of them after pulling the tank out. I've also replaced the high pressure pump under the floor at the drivers seat. The fuel filter is there also.
There is a junction where fuel lines meet about mid ways that looks like it would contain a large filter. From what I can find out it doesn't use a filter in there. I've replaced a relay for the starting system at the right front by the battery. There are a couple of relays sitting there together at the edge of the hood when it is closed. They tend to build up crud and lose the good mechanical connection. Then it is click click click when you turn the key.
I did have one emission valve on the back of the motor to blow apart. A rather straight forward disconnect
of the hoses and unscrew the base of it and install a new one. Probably rusted sitting so much at the previous owners shop.
Otherwise the Econoline Vans seem to have a pretty good reputation.
I just wasn't aware of Ford putting Cleveland's in them. Again because that was built as a Class B....Whatever company made the conversion may have special ordered them so they would have a bit more power.
