I acquired a '61 Thunderbird in the past year and it’s engine had been replaced with an 80’s 5.0 HO from a GT Mustang. The original 390 is still in great condition, it just needed it’s valve seals replaced and the old owner wanted another engine in there in the meantime. Unfortunately, the Thunderbird only ever had a wide-block engine which means there was never a need for Ford to make it a bolt-on bracket but rather a simple weld. The owner before me cut the frame to make the new brackets fit a small-block engine rather than the big-block. The issue is that none of my local shops are willing to attempt to do the weld job to get the frame where it needs to be without the dimensions needed for said frame. I was wondering if the dimensions were recorded somewhere so that I can get the engine put back in? I bought an OEM shop manual for it and no dice. I really don’t want to have to restomod the car when I have a perfectly good original 390 ready to be put in.
fyi: I know a bit about this kind of thing but not a whole lot. My mechanic who used to work for Mercury in the 70’s filled in the blanks for me. If I’m off in someway, I apologize.
