Well first, thanx for your reply, I see the
oil gallery on the left hand side of the block w/ the 5 tapped/threaded unplugged holes. I can also tell that it isn't a 427 SOHC Cammer block, It doesn't have the
oil gallery @ the rear left cylinder deck on the block!!!
It does show the 8 pronounced ribs on the passenger side of the block corelating to the 3 blocks that were made to be hydraulic lifter able, though I can not see the
oil galleries on either side of the cam journal opening on the very back of the block to confirm this.
The seller painted the block, so I also can't tell for sure if the freeze plugs are steel or brass. Steel for street, Brass for marine if they haven't been replaced! Well enough said, I also hope this will help other perspective block seekers out there,, Cheers!!!
