OK, I finally got the new harmonic balancer but the timing mark is not in the same place. I went back and looked online and I see the same part number for all the 350 engines for the years this engine probably from. I am trying to make sure I get the right one this time. I looked up the block casting numbers.
Engine Block Codes for CID 350
Casting Years CID HP Main Notes
10066038 1994 350 4 Goodwrench crate motor, 2-piece rear seal, "Hecho en Mexico"
That is much newer than I thought it was. The guy I got it from said it was in a motor home that he guessed was from the early 1980s.
Is the diagram enaberif posted about 8 posts ago, mine is the 10 degree kind (which the diagram says is from 69 to Mid 80s. The one I just received is the 30 degree kind (post 1986). So my engine is really cobbled together from disparate parts it seems. Newer block, older style harmonic balancer, etc.
Anyway I just want to get the right Harmonic Balancer but can't figure out how to specify it on the websites. I got the new one from O'Reilly.
This is the wrong one:
