    Help Push Rods

    I just bought a comp cam the duration at .050" lift is 224/230 (int./exh.) lift with 1.7 rockers is .581"/.588" (int./exh.) on 114 lsa. I need to know if I need different push rods. If someone could help me out and let me know it would be great.

    Only way to know....is to measure.

    You likely don't, but at minimum you will want hardened pushrods and upgraded valvesprings.

    7.4's will do you fine. Like said earlier Chromoly pushrods and new valve springs would be wise to change also.

    I did buy new valve springs, and i was going to upgrade my push rods, I was just needing to know if I could buy standard length.

    I have seen the aftermarket cams base circle smaller the stock and it mite take a 7.425 instead of 7.4 but measure and know for a fact.

    Have you made any changes to your Cylinder Heads?? Lifters??? If not the guys responses are correct: 7.4 or 7.425 hardened chromoly + springs. 7.4 may increase the valvetrain noise slightly, 7.425 should be right on with the different base circle of Comp Cams WITH XER lobes.........
