    Running very rich

    Ok I just had got my new motor installed and had a 224/228 - 277/281 ,
    .534 / .537 112 lobe comp cam installed, ported heads with 2.02 / 1.57 valves, longtubes, 92mm fast intake, 2800 stall, pro magnum rollers 1.75, no cats, air, egr and I've put a couple heat cycles on the motor but its running really rich? I have no codes being displayed....I need to get this thing going but I believe I have a slight smell of gass in the oil.....would this be a tuning problem or if my pcv system was kinked could this expose my oil to gas?

    check the rpm "window" for the cam. if you have a choppy idle and no cats your probably gonna smell a little gas. a tune would probably help little, and you would pick up a little more power there.

    try reving up to around 2.5k and see if the smell goes away.

    Post the base file that you are using to get started with.

    If you are running a stock file, we're gonna say "DUH! of course it's rich" and it needs some tuning.
