  • Cam question...need roller rockers.

    I am looking at a new cam for the '97 along with the recommended valve springs. What roller rockers are good for the LT1. I am looking for more of a low cost 1.6 roller rocker until I can do the rebuild in about three years. Does the lifters need to be changed for this cam, or are the stock ones adequate; I have about 94K on them, though. I need to pull the intake to fix the leak, and I thought I would pull the heads, and port the pockets at the same time...get the valves reseated.

    Oh, are the shorty headers worth the money, or should I stay with the manifolds?

    COMP CAMS 1993-97 5.7L LT1

    266/276 degrees advertised duration, computer controlled, hydraulic, Xtreme RPM, roller cam
    Duration at .050 in. cam lift: 210 intake/220 exhaust
    Gross valve lift: .500 in. intake/.510 in. exhaust
    Lobe separation: 114 degrees
    RPM range: 1,000 to 5,000

    Anyhow, I thought about going a little more aggressive, but I am not interested in getting a new program at this time, but a little more power until I rebuild the motor. Supposedly, this one works on a stock programmed PCM.

    I am running crane gold rollers. They are pricey, but they are holding real nice. I have also run comp pro magnum rollers in the past and are also a nice rocker. They are about 50 bucks cheaper.

    you can reuse your old lifters, they have a roller tip and do not often wear out. Just make sure they are in good shape when you pull the heads.

      The 218/224 cam needs a little reprogram, but is
      great on the stock converter.

      I used the crane gold rr's.

      You probably have a burnt lifter or 2 if you've
      run the car hard.

      Definitely check them out and the cam lobes too
      for burn marks.
