timing sounds like the issueWhen the cylinders get hot, there is almost a predetonation occuring which is causing your engine to try to run backwards. If you have quite a few miles on the engine, your timing chain could be streched to its limits and the valve timing is all wrong.....you...

Here's my 1983 F-250 w/460It is a non emission 1983 460. It is bare to the bones, but I want to put the cab from my '89 150 XLT Lariat on to it to get all the bells and whistles. Any helpful hints on the project will be accepted.

Does anyone know if the cab from my 1989 F-150 will fit in place of the cab of my 1983 F-250?
