The numbers you have there are not the right ones. Look on the frame for a serial number that is at least 13 digits. Then I can tell you what you have. By the pics it is definitly a explorer. 300 or 400 is the question, is there a radiator or no?

 

You can tell by the fins on the cyl that it is air cooled, so its the 300

 

Holy cow, I think that's the TWC model. (Third world country)!!!! Still runs, I'd just keep beating it. A reliability experiment.

 

that was another give away for me also..

that was fun i wish we had one of these every day...lol...
