Jim (dunno if this will make it to the List), My 61 Dodge T.S.B. states that for Dodge (anyway) , the "R" is a "Series"-number, and that it appears on SLANT-6's (that's the R 17 and R 22 that I mentioned, for the 170 & 225 blocks) as well as on all the V/8's . It looks like the "R" may have designated all 1961 MoPar engines.
