To the original poster though.... I would just look for a newer 351w to swap in place of the 302. Your trans and flywheel/flexplate will bolt up and all 351's are the same 28oz balance as early 302's. The intake wont swap over but the other 98% of the parts will. Easy upgrade for a nice bump in power.
One of those needle in a haystack motors cost me a bunch of money and some grey hair,thats why I brought it up.lol
I bought a mint 77 Mustang 2 with a blown up 302 in it.It was clean as could be and 100% stock.I hated fords but figured any little car with a big motor should be fun.I bought a built 289 from a 65 mustang for it and was shocked when it wouldnt fit on the same engine stand the 302 just came off of.The v8 mustang 2 used a c4 with a tiny bellhousing,flexplate,and convertor.There was no way to use the 5 bolt 289 in the mustang 2 so I sold the whole project.
