I have been offered a free 1992 300 inline 6 and my truck is a 1988 with a 300 inline 6 with close to 400,000 original miles on it. The existing engine is starting to need some work. go figure. I guess what I need to know is , is this swap possible and if so will there be any modifications to make. I realize that I will probally have to use some of the existing components but if anyone has some guidence to this swap please let me know.thanks
