Does anyone know what engines were available in the 60s? 1963 in specific. My truck had a V8 which was removed before I got the truck, but it originally had a straight 6. Does a 300 straight 6 use the same mounts as a 170 aka 171 straight 6?

 

If you are talking pickups, you have the 292 V8 and the 223 (and possibly the 262) six in 1963.
