I am not sure if this is the right place to ask this, but I just purchased a project vehicle and it appears to have a old 305 in it, previous owner was unaware of the origin of this vehicles engine so I thought I would try here. It looks like it has a casting number of 140 0202, but I can’t find any info that relates to it… I am attaching a picture also to see if you guys might have any insight, thanks

My 10/82 built 1983 G20 had black paint over blue paint from GM.
The Suffix code behind the water pump should give more info on what it came from the factory as.
