The /6 engine in my 73 Swinger is not original to the car as the vin doesn't match. The guy I bought it from said it was a 71 engine. It doesn't really matter in the long run, but I'd like to know. I googled it and read a few articles and posts on dating the motor but they didn't really help. The numbers on the block near the alternator are GW 225 R 3553.
I know G was the series code for 71, but what about the W? I thought "warranty" but it has a vin stamped in the correct location. And the R? Raised block? 3553?
Anyone know off hand?
