360-1 Casting better?

So then the dash numbers really don’t mean anything as far as any number being better for strength. Kim

Yup. In theory later revision numbers may have had more running changes incorporated into them, but even that’s not a guarantee because the revision numbers don’t correlate exactly to dates, some cores/molds needed more repairs than others.

Doug Dutra said he never looked at the “dash numbers” in his article, except one specific case which was more about the core revision itself (thicker webs) than the dash number itself.
