    Recommendations for fuel pump push rod needed to complete engine build. Plan on using Holley 12-440-11 mechanical fuel pump.

    Engine block is 1974

    I believe the correct fuel pump push rod length is 3.220

    Get the Comp rod with the hardened tip.

      Are you using a flat tappet or roller cam?

          Make sure it measures 3.220 or real close.

          Definitely do not buy a Howards Cams. This one only has 1k miles on it.

              Seems as though you could case harden one yourself.
              I have a friend that does steel treating, I'll bet he could take almost any of these purchased parts and make one pretty indestructable.

              Yeah, don't get the Comp one or the Howard's one either. My 440 ate both like candy.
              Mopar part number: 2463921
              A couple places still have them.
