What Blykins said. I see some nice vintage Holmon-Moody stuff. Don't forget the casting numbers on the intake. A pic of the driver's side of block and the back of the block (without flywheel) would tell us if it's a side-oiler or center-oiler. We are looking for the
oil passage running along the side of the block and an
oil pressure relief at the lower left (driver side) on the back of the block. I don't see ribbing on the side of the block, which would indicate an over-the-counter replacement block. So far, so good!
