The {{convert|1897|cc|L|1|abbr=on|order=flip}} '''3R''' family was produced from 1959 through 1968.

When introduced it had a 7.7:1 compression ratio. In 1960 the 3R was uprated to 8:1 and the '''3R-B''' version was offered from 1960 through 1968 with the old 7.7:1 compression ratio. The '''3R-C''' was introduced to comply with California emissions laws. The '''3R-LPG''' variant was produced for the last five years.
