Thanks for all your suggestions! I think im starting to lean in the slant 6 direction, as I dont think an engine swap is within my ability as a mechanic just yet. Im sure I will have more opportunities in the future to fulfill my v8 crave.
That's what I would do also.
I like the 225 A cars. A real pleasure for cruising around. My favorite of the many I've owned was a 68 4dr, auto ac, ps, pb Dart. That was a great do everything car. It certainly earned my respect.
If I had a clean 2dr 225 A car and wanted a v8, it would have to run like the 69 GTS I had in 78. It would be done from a 91-93 Dakota v8 auto 3.91 posi rear doner. All of it. Which I happen to have but wouldn't use because it's in very good condition and everyone in the family likes driving it.
I wouldn't go the 273 route.
