Rather than start a new thread I figured I would bump this one...
Found a 'long-block' and am getting conflicting info from the seller. Did plenty of searching and found this little breakdown

Im a little confused because this one starts with a 640 ####
So is this a 1980 3.0 SC motor or a 1970 ...2.2 or something?
Case has 901.105.111.0R & 901.101.101.3R ...
Can anyone clarify this for me? I thought the 3.0 would've been a 930 on the case, not 901
Be kind, I've been a dreamer for too long and am finally trying to start collecting pieces to start building
