    Cam Help for Lightly Modded 02 WS6

    I'm trying to decide on my cam swap and need a lil advice. I don't wanna go outragous but I want something that is gonna lope pretty hard. By the time the cam gets installed car will have the following:

    Ported Heads with New Stainless Valves and Recommended Springs
    Ported TB
    Weiand Intake
    Aeromotive Fuel Rails w/ New Injectors (36lb be good?)
    1.8 Shaft Rocker
    Comp Hi-Tech Pushrods
    Double Roller Timing Chain
    MSD Coil Packs
    Kooks Headers and Off-Road Y-Pipe
    Corsa Cat-Back

    I was thinking like a .560 Lift, that be too big? I want it to stay a Street Racing/Road Course car.

    go .580s and on a 112 lsa. wont be bad to tune and will make it scream and will idle hard and choppy like you want. hell, call comp cams or texas speed, tell them your mods and aspirations and theyll match you up accordingly.

    keep 1.7 rockers can you can go bigger with the cam. there is no need for the 1.8 and they will greatly hinder your cam possibilities. the lift you are thinking would be fine, you should be fine all the way up to .600 but the duration matters more and that is what will determine how your car behaves. just poke around at some of the other cam threads and check out the advise given to other people.

    i agree with above, keep the stock rockers.
    stock injectors and coils are fine.
    ls2 timing chain instead of a double.
    behive springs rated past 600 lift are a good idea.
    a 228/228 cam with a 112 lsa sounds like what you want.

    in a road racing application, the 115 LSA will give a nice long powerband.

    and keep the 1.8 shafts.

    Is it possible to swap the 4 and 7 firing order like I did in my dirt car? That really broadend up the power band alot. Is the firing order the same as the pre 85 blocks? We ran those with carbs.
