    I'm thinking about getting a 58 mm throttle body, as I have headers and cat back and feel that getting more air in to match the efficiency I have after combustion would be good.

    Anyone have any advice or think it's not worth it?

    What about brands? I've seen them from 160 to over 330 on fleabay.

    Thanks for the help.

    If all you've done is headers/exhaust, don't waste your money on a TB yet.

    pretty much. and with a 58mm you have to port match the intake manifold. go with a 52

    :ugh:
    you also have to port match for the 52.

    the stock intake opening size on lt1 AND lt4 intakes is 48 mm..... so your not going to see much gain from either unless you port match..

    so if you feel that you MUST have one, or plan on port matching...... just buy the 58mm......don't ever waste money on a worthless 52mm....


    edit.... a cold air intake will help you way more at this point.

    Or learn to tune yourself and stab a cheap cam in there.

    Keep an eye out for split BLMs after install. Also watch BBKs as they whistle through the IAC port like a steam whistle.

    SOTP difference and (serpentine belt squeaking during shifts :ugh:) does not transfer over to 10-20hp increase.

    I honestly don't believe wiht a basically stock LT1 it's worth going to a bigger TB yet, save that money and buy a cam and a tune.

    Thanks guys- looks like my money is better spent on a cam. That was the direction I'd planned to go next anyway, but saw that article.

    The only TB I would recommend is an Arizona Speed & Marine. They are expensive but they are worth it.
