[Woodz428]

The block has the castings in the back for side oiler galleys, but there doesn't appear or be visible the side casting. I had a 428 CJ block cast like that( from a '69 Canadian Eliminator), but have not seen a 427 block that way. It's listed as a 427 in one of the casting # books I have,actually twice, once as a side oiler the other has no indication as to whether it is side oiler or center, all the other #'s do. It may be a replacement 427 block for a center oiler and uses some of the side-oiler molds. Since the side oiler was standard issue by that year, it should be a side oiler or a replacement block if it is a 427 originally. I also have a 390 ('64) block with crossbolt castings nobs, but no crossbolts. Ford mix and matched patterns for FEs and this is likely one.
I checked the book before closing the post and see that the # is also a 428 PI solid lifter block. I think I'd have it sonic checked.
Is it a solid lifter or drilled for hydraulics?
