Generally that's a good match. Some use a 3:55 rear. I would be concerned that your 216 could handle a constant 2K rpm, although
I really don't know for sure. Maybe others here do. It just wasn't built for that continuos strain, just really more low end easy running. In any case, if you do want to run at 65mph, you better upgrade to better brakes and rebuild the front end or at least make sure it's tight.
