For those who think the old Pony is not road worthy, I just finished a 2,275.5 mile trip in my 1965 modified SIX cylinder coupe. A .060" over bored, 2-barrel, exhaust work, hot ignition with modified suspension, front disc brakes, air conditioning and 15" radials. The SIX will not out run a V8 but it has a place in the Pony corral. I had no trouble staying with guys in the NASCAR lane doing 75+ and passing was not a problem either. I have always been a big V8 fan and I still am, but do not sell the Inline 6 with 7 main bearings short. It now has about 35 more HP than when new with taller rear tires, which help it get 24.5 MPG without Overdrive...and the AC was on all the way.
