    I got a 1989 Camaro Iroc

    This winter i want to pull the motor and rebuild due to the KM's its got 218,000 km I am wondering what cams, heads, intakes to look in to. Its going to be used for 1/4 Mile but also some daily driving like maby once a week. not much town or city driving. Also what tuner do you guys recomend.

    Thanks,
    David

    That's a pretty broad question. You have the TPI motor, not the LT1 motor btw. Do you want a forced induction motor? NA? Nitrous, etc... What are your goals for the car (powerwise, driveability, emissions, etc.)?


    Some generic information I can give to you though.... you'll want to ditch the stock TPI heads and intake setup. There are numerous aftermarket runner and plenum setups that will be much better than stock. As for heads... if you want cheap and good performing heads, the vortec heads will bolt right on, and now places make manifold bases that work with the vortec ports. The vortec heads are cheap, plentiful, and can be ported to flow very well (they flow great stock).

    David, have you considered swapping the engine entirely? If you stick w/TPI, you'll definitely want to toss the stock intake, plenum and runners. Porting them helps, but you can only take them so far. Look into an LT1 swap, their cheap enough, nowadays...

    I have thought about that, If i decided to keep it i was going to throw a cam in it and a set of heads and intake.

    It honestly depends on you're goals with the car. Keeping it Tunes Port Injected would be easier, and you can always stroke the stock block out to 383 cubic inches. You can go even further than that of course, but again, depends on you're goals. You have so much to choose from in reference to H/C/I (heads, cam and intake) selections....

    I'm running 12.2s with my stroked '87 TPI car. I have installed tons of stuff, but mainly of interest to you is the Accel SuperRam intake.

    As shown above, check out www.thirdgen.org
