So if you've seen my other post regarding my '55 bearing problem, this is a follow up. In that thread it was mentioned that a block using doweled bearings could be modified by adding the notch to accept the tangs that are used on later '56-'63 blocks, the 690M-10's.

Anyone have info, pics, anything on that. Seems like it may be my only option at this point. Thanks!
