ID help with engine, rear end and tranny

I have done a bunch of searches for the Trans without much luck. It is for sure a 4 on the floor, with the granny low gear. The rear end however I am pretty sure of it being original to the truck.
I would love to know the year of the engine! Engine has stamped 1M0281 9VP on front passenger side head. The rear bell housing casting number on the drivers side is 10066036 Hecho en Mexico. On the passenger side, it has a 99 (or 66?) cast next to the date dial.
In my research I believe it to be a GM Goodwrench crate 350 V8. Some vague information I found online stated it was “350, 4 bolt, Goodwrench crate engine, 2 piece rear seal, ‘86 and up” But, not sure how reliable that is.
Transmission photos show a casting number E228, 2, GM, 3901127 and, another casting number right by what I guess is a Trans fluid temp sender? GM, 0901191, then below that a K2...I think I need to clean it off better.
