Technical Carter AFB Help

I pulled one off my 283 2bolt block to try and figure out the kit I need to get for it, but I"m not getting a lot of info for a 4169s M coded Carter. I think the numbers after the M code are 57.

Any help would be nice.

 

It's from a '66 Cadillac.

 

Hmm, this block seems to be a conglomeration. Thanks for the info!
