    Roller Rocker Arms

    I am considering a set of roller rocker arms for my 2001 Z28. I see a lot of suppliers out there. SLP sets are about $500. I need input on what to avoid.

    I would avoid everything man.

    The stock ls1 rockers are fine for almost any application. I would just cam the car and be done with it. 500 is alot of money for very little gain.

    not all rocker arms are useless. depends on which ones you buy. i use the vinci/crane 1.8 accelerated lift rockers on the wife's car. this is a dyno back when it had the stock cam.

    dyno 9 before
    dyno 11 500 miles later
    dyno 14 10 months later

    be careful with accelerated lift rockers with a higher lift cam. dont really need that at all.

    I allready bought a set of Crane accelerated lift roller rocker arms, got them on ebay. My new set up will include;
    SLP Cold air induction
    K@N Filter
    SLP Airbox lid
    Granatelli Mass Air Flow(W/cold air tuning)
    Throttle body bored out to 78mm
    Crane roller rocker arms
    JBA Shorty headers
    SLP Y pipe
    160 Thermostat
    Throttle body bypass
    reprogram with a Hypertech 3
    I wonder how much horsepower I will make?

    Won't happen.

    There have been some cases (believe it or not) where people are actually losing power in the upper rpm range with high ratio rocker arms. There have been a couple of threads about that in the *other* forum.
