That's cool. I saw an article in an older Falcon book where they stuff a built 312 T-Bird motor in a '60 Falcon. It was pretty trick looking. I'm going the route of a 347 Stroker with EFI. I got a 5.0 roller block from an 86/7 Town Car with a roller EFI 5.0 in it. I'm going to top it with AFR heads, and an aftermarket EFI kit from FAST, and it should be in the 450+ range on the HP side.
