Got an early Ford small block with a factory PCV system? Then you know the correct Ford or Autolite PCV valve can be hard to locate and costly.

Here's an alternative, an NOS AC-Delco valve, one of the best service parts brands in the business. This valve is correct for 61-63 221, 260 and 289 and is the same heavy gauge, plated and machined valve as the Ford original. A lot less pricey too..
