After several years of not getting much done on my truck (I was a member of the site in the past), I am ready to get going on it. I remember several years ago (I cannot remember if it was before or after the great M715Zone site crash or not) that someone had swapped in a Ford 390 into an M715. Well, I would like to do the same. Does anyone remember more details on the swap? Is the person who did the swap still on the forum? I currently have a 390 in the process of rebuild and a divorced NP435 that has recently been rebuilt. In conjunction with the engine swap, I am planning on rewiring the truck (to 12v) to clean up the mess a VFD left behind. I plan on keeping the NP200 and axles ... for now. I am also curious if any of ya'll are close to the Clear Lake area of Houston. It would be great to share company with some like mind folks.
