I have these old valve covers. Definitely not new repops. Heavy finned Edelbrock covers that I believe are olds or Buick based on the bolt holes. Holes are too far in the center to be Y block I believe. The inside has "1957 8" cast into the underside of the top. Anyone know for sure what these would fit? Thanks!
I'd agree with you as on the Buick the hold-down bolts are not centered in the cover while the Olds are.
