This came out of my 66 327/350. It's the casting number on the pump. Is this just the standard SB oil pump? Thanks.

Yes, it's a standard volume pump casting. However, there's no way to tell if it's standard pressure or high pressure----both pumps used exactly the same body and cover. The only difference is the relief spring installed in the cover. If the pump is original to the car, it will have a standard pressure spring installed.In Appreciation of John Hinckley -
