Super cool! Will be great for your son to learn on, I know I learned plenty on mine. Get some good hog ring pliers and the interior will be a fun project.
There is a pretty good technical forum that is focused on the Ford six performance, fordsix.com Nothing like here but the technical help is great.
Mine is a 3 speed and pretty much V8 stuff from the bellhousing back. In '67 they started using the same 3 speed for the V8 and 6cyl cars. The 3 speed in the 6cy cars for '66 and '65 did not have a synchro first so by the time I got mine as a 17yo in 1991 the trans was pretty tired.
Once my son was born in 2006, we had two kids and I was pretty into the Pcar scene by then and since my Mustang sat up on a lift in the garage it was one of those out of site out of mind type deals. Now that my son is a senior in high school and into cars (he drives a 5 speed 5.0 Fox body Mustang) he has been pushing to get it running. All we have left are new front suspension and 5 lug disc brake conversion and hope to start that next week, as the car runs now.
Here is a picture of the Offenhauser 3x1 intake with Webers on it. It is a progressive linkage and runs on the center carb until you give it gas. It also has a 6 into 2 header on it going into a couple of Flowmasters and I think sounds cool.
Ignore the horrible engine bay paint, lets just say as a teenager the battery may have come loose and a corner chopped off by the fan. When I opened the hood to see hat the heck was going on I got battery acid sprayed on me. Oh to be young again....
