I was wondering if anyone could confirm this is a 155 in my oliver 550.
block numbers are 180220L 159002A 10214. Thanks

Look at your intake manifold. If the carb mount it straight down centered, it's a 144. If it's offset toward the front, it a 155. It had to be moved to the front position to accommodate the bigger carb to clear the starter.---HTH---Kent

If it is a diesel the intake manifold will attach different to. 159 002a is a late block.
