Hello I am hoping someone can help with ID of an Engine block and what year it came from & what it can go into. I've tried reading through other sites to no avail so here goes: I know its a B20, from there it gets vague a friend thought it might be a B20b engine twin carb model from 69 or 70. It has the numbers of 4969 then 4 I (letter) or 1 (number), Dad doesn't have great eyesight in the dark shadows of the garage, then it also has the numbers of either 419803 or 419303. Its been rebuilt and properly stored and plugged. Dad wants it gone, I'd like to be able to save it from the scrap and make sure it gets put back in use. If I knew more about it it would be a great help. I'm trying a hard to save up for 1 of the nice 544 wagons. Any help would be appreciated. Thank you!
