I have several. A 1965 Falcon Sprint w/a 30 over 302-4bbl on top of an aluminum intake-mild street cam-headers-4 speed. My son and I restored the car 35+ years ago and have driven it to much of the eastern/northeastern part of the country. We are now working on a 66 Mustang coupe restomod. It has a 281 (4.6) aluminum 4 cam 4 valve engine from an 03 Mach 1. We also used the 5 speed from the 03. We also adapted the 03 shaker hood to fit the 66. Mustang 2 front end and I won’t bore you with the rest of it. You can see the Falcon in my profile.
In 1965 one of my friends had a 65 Falcon. I can’t recall if it was a 260 or 289 but it was pretty hot. It had an auto on the floor, nothing done to it but I always wanted one of them.
I’m not a Ford guy, but yours are SWEET!
