    More Cam Help

    I'm looking at throwing a cam in my '99 TA this winter, just not sure on which cam I want to go with yet. Car is not a DD. Hoping for 400 hp 400 torque with worked heads. I'm leaning towards TSP Torquer V3. Any thoughts? Will my TA fall on its face out of the hole with that much lift?

    Current mods: Lid, smooth bellows, LT's, ORY, Loud Mouth, SFC, STB, Stage II Clutch, Aluminium Flywheel.

    Planned this winter with cam install: 12 bolt with 3.73's, Ls6 Oil pump, double roller timing chain, PRC springs, ported stock heads, 25% UD Pulley, Fast 92 intake with 92mm TB.

    I would say 224/228-581/581 110lsa+4 this should do it easy w/your mods
    and plenty of torque not to fall on it face!

    OK Thanks...Do you think I could go with anymore lift??? I don't want to do all the work of a cam install just to strip it down 2 months afterwards because I went too small the first time.

    Yeah '
    but stock head won't flow more than about 600 lift and if you go
    different head w /smaller chamber you'll have to watch piston to valve clearence

    So would it be more beneficial ($ vs. performance gains) to port and polish the stock heads or splurge for new heads?

    ALOT OF PEOPLE RUN DIFFERENT COMBO'S BUT WITH DIFFERENT HEADS THAT HAVE A SMALLER COMBUSTION CHAMBER IT UP'S THE COMPRESSION AND GIVE YOU MORE OF THE POWER & TORQUE FEEL DOWN LOW , BUT IN TRADE OFF IT PUTS THE VALVES CLOSER TO THE PISTONS ! SO WITH THIS SETUP I WOULD GO WITH THIS- TSP XS Series Camshaft:
    Magic Stick V.3 237/242 .603/.609" THE HEADS WILL GIVE THE POWER DOWN LOW SO YOUR CAR WONT (fall on it's face) AND THIS CAM WILL WORK IN THE UPPER RPM'S AND STILL HAVE CLEARENCE WITHOUT HAVEING TO FLY CUT PISTONS

    FALSE. Bigger cam, bigger #s. There's a reason why the T Rex is listed so many times on LS1 Techs fastest cam only list. I run a 232/236, 613/613, 111'+1 cam only. Intake lift is high on that cam but the PRC duals can handle it. I'd go MS3 myself.
