    Anyone know of a machine shop that will bore out a GM throttle body?
    Need to get a 350 TB bored to a 454 TB.
    Thanks,
    Joe

    I'm pretty sure you can't bore out a 350 TB that much. The size difference is too great. You'd go through the wall. Stock bore size on a 350 TB unit is 1 11/16" and bored most are 1 13/16". Stock 454 TB is 2" and bored are 2 1/16". Check out turbocity.com, cfm-tech.com, and there's also a guy on ebay who's substantially cheaper who does them (i'm not vouching for him though). IIRC the guy on ebay sells 454 TBs without a core return neccesary, so you might want to check that out.

    Thanks for the info. Have to check on that.
    I do have the 454 tb, but does not have provisions for the tv cable (700r trans) and harness connections are different. Hmm, guess I,ll have to investigate a little further.

    The harness can easily be rewired, I think the pins will just switch to the new housing IIRC. Not sure on the TV cable, is it 75 ohm coax? ;)

    Ummm... So does anyone know of a good machine shop? I may consider doing a little motor work if I can find a decent one. At any rate, it's nice to have a place to go if you need to. Thanks...
