So long story short my brother in law is an older Olds collector/lover that has moved into his old age. He had to sell off his 58 Olds and his other toys and is cleaning out a bunch of his stuff before moving to a senior center.

He is not internet savy and asked me to research some information for him. He has some Michigan crankshaft bearings that he is going to sell (I assume??) and he asked me if I could find out for which engine the bearings are used. He said it is either the Olds 371 or a 394 as those were the two engines he had in his cars but his old memory just cannot recall the details anymore.

I did the Google thing extensively and I have used the search function on your forum as well with no success. I did discover that Michigan bearings are no longer made and attempted to find a cross over from Clevite without success.

So the info on the bearings is as follows:
Michigan
1041 K standard
4041
MS 485 P

Thanks for any info guys.
Regards,
Dave.
