The high volume LA engine oil pump I have is the same body casting as the stock A poly pumps I have in all 4 poly mid 60's engines I have, the later stock LA pumps look differant. Even so the bolt pattern and drive shaft should be the same in both type pumps. The LA blocks are just a lighter type casting of the A block with few changes, such as were the head oil return hole is; as a mater of fact I have a friend that has put poly heads on a LA block and it work great, a few miner mod's and bolt them on.
