hi all. i'm in the middle of pulling down 2 flat head 6 motors for my old plymouth and realised i had very little info on them. both are stamped somehwat oddly. any help would be appreciated. so this one reads PE2 694 The other (which i have no picture of currently) is identical minus paint and its stamp reads KEW 2PF 2792 any info on this at all would be much appreciated. i have no idea how to decipher these at all.
