All automatic trans back in the day where made at one plant - the Kokomo Trans Plant. There are no external differences between a big block and hemi 727. As I suspected. Now what is the prefix for the Kokomo plant in the pan rail number sequence? I see one with a J xxxxxxx and one with a PK xxxxxxx

Someone opined that this means it is a parts room replacement built at a date later than the model year. The example below is for a '67-'68 model year but the build date is mid-'72.

I have ran into the question of date before where some were dated with the normal 10,000 day calendar. But have noticed that 67 and back the date doesn't seem to be the same. I have a 67 440 HP trans and I believe that it stamped H for the plant, then the part number, followed by the date. but the date is not correct for the year. I have seen them stamped PK, H, and J before the part number. Would like to know more on the dating as well. I can try to get pictures maybe later, if that helps. Matt

Here is a picture of a 1966 hemi 727 that is still attached to a very unmolested 66 hemi engine. The engine appears to still have the original fan belt and a M embossed mopar oil filter on it. It was supposed to have been pulled and shelved in 1969, so I have no reason not to believe it is factory original like the rest of the engine. Matt
