My personal experience at least is that any cars I've ever played with have not had a full syncro in 65 or older. The article you mention is what I have always believed to be accurate.
Just checked the 65-76 Impala parts book. It says 327 and 409 in 65 had the 66 and newer style 3 speed, smaller engines had the regular old grind into low and reverse 3 speed!

I was going to go against the grain and say it wasn't '66 as my Chiefy with a 3-thro and original 250ci mill always snarled at me if I didn't wait a few seconds or shift to 3rd first before going into 1st...
Non-syncro through 1965, but a h.d. fully-syncro was offered starting in 1965, the h.d Warner T-16. It was an option on 1965 327s and was included as base on 1965 409s. For 1966 it was included with the 396 & 427; meanwhile the Saginaw became fully syncronized for 1966 and was used through the 327s. Ratios on the Saginaw originally were 2.94:1 low on sixes & 283s, 2.47 low on 327, 348 & 409s (big mistake to use one behind a 409). For 1964 they were improved and the 2.47 low version became a 2.58 low. For 1966 the 2.94 low became the 2.85 low; the 2.58 low became the 2.54 low. The h.d. Warner was a 2.41 low but they also sometimes offered a 2.86 low behind sixes & 283, but such instances were rare and just for the U.S.
