Mine is 1490+ and has the folding wing. Not any of the squirter block details under the hood though.

 

Early style intake and oil filler can't be kept as limit for squirter block. I believe they were changed to "normal" version long before squirters were left off from block. There is thread in here somewhere with engine numbers for squirter blocks. Its best quide for estimate which ones have them. Its also good to keep in mind that manual and automatic gearbox cars have separate engine number sequence. This sometimes confuses things even more.

 

^^^^^^^^Thanks for the info.

I had a chance to look up a prev thread that discussed block numbers. I found this post from Erkka:

81H00677 = '87 M28/41 manual gearbox car engine
81H05746 = '87 M28/42 automatic gearbox car engine

First manual engine was 00501 and first automatic engine was 05001.
00677 = 177th manual engine
05746 = 746th automatic engine
Depending on how many automatic vs manual cars were made its possible 05746 was made before 00677.

Its impossible to know how factory stopped adding squirters. Unless some specific limit is found also for automatic engines its always possible they continued getting last squirter blocks later than manual cars.
