    you think a ported and polished stock t.b. is as good as say buying an aftermarket 78 or 80mm??

    Depends on what you're aiming for.

    It really depends.

    When my car was cammed (226/234 554/575 112) and I got the stock TB ported and polished....the computer certainly knew something was up.
    Took a while to adjust to it.
    I would assume it picked up a little power. Couldn't feel the 4-5 RWHP though.

    When i just had a lid and cutout i added a ported tb and i felt a pretty good gain in the upper RPM's. I doubt that i will ever buy and aftermarket TB unless i have to upgrade to a 90/90 setup in the future.

    Use some carb or brake cleaner.
