could someone at least explain to me why it is hard to believe that I have a 2.0? I am an ASE Master Tech, not a do it yourselfer. I wouldn't doubt that this is not the original engine. I would like to figure out what I have so I know for future reference how to locate parts for it.

BTW, I have a timing belt on order, it will be here in the morning and I am 99.9% sure it is the right one. It is a Gates T013. 122 teeth 19mm wide 45.75" long and has trapazoidal teeth. Took a lot of research to find it. Near as I can tell it fits late 70's dodge/plymouth 1.6l as well as late 70's pintos.

Could someone have put a 1.6 in my truck? I have alldata and Haynes manuals. I also have Autodata timing belt book. They all show the exact pictures of my engine and say it is a 2.0. I have also talked to a Mitsu specialist who says that some of these engines came with these diff belts and they were supposed to have the pulleys changed at the first belt replacement interval. I just need some help clarifying some stuff...
