Type 901/xx Engine Build #'s

Thanks for the clarification. If you can find and post the case half casting dates and/or the pairing number that would be very useful.

Hi Dave,

I just posted a question on Pelican, about this number, just to find out you have it covered. Great news! So, here is my contribution to your research:




Regards,

Thanks, very interesting to see the double stamping of the type #.

Dave

Here's a bunch more from my shelf stock.

I have only included the Mg cases

Wow, lots of work, thanks. A couple of things have changed in my research since starting this thread. I've been adding the case casting numbers ending 101.xx and 102.xx to track their evolution, and the case casting dates to assist tracking the evolution. If possible, the addition of these data points would help a lot.

6196736 should have a build #, but if not, then that is significant.

Jerry, 6258522 probably should be 6298522 since third digit is the year.
