Default 500EFI stock injector size

Did the 500EFIs come with 38# injectors?

That is what I recall reading on here somewhere or another, however my 454 MAG MPIs use the 44lb short injector so I don't know for sure, but it seems they would not use a 38.

Well so far I have read they came with 36, 38 or 42. Trying to get a definite answer.

Did different years have different size injectors? Just talked to a member that has his 500EFI injectors for sale and they are 36#.
