    In mine, they made the opening bigger so the edge almost came to a point and tapered in to the butterfly, they mostly get rid of the bump that is like a half inch in front of the butterfly and stop right before (maybe 1/16) the butterfly so you dont have sealing issues. they then also do they stop modification, http://www.installuniversity.com/ins..._bump_stop.htm

    Porting the stock TB is a common mod. Most upgrade to an LS6 or aftermarket intake rather than port the LS1 intake.

    You can do it for a few extra hp, but if you've got it apart you might as well throw a better intake and tb on. You'll get more performance out of upgrading.
    It's not how fast you can go. It's how fast you can get there.

    Agree! No sence pissin' around with time in modding an old set up for maybe a couple ponies not a bad thing tho. Of course if your strapped for cash and have no other options..

    +1. Its best to just upgrade if you can. Ported TB or intake is not the worst option, especially if you cant fork out cash on a newer, bigger TB. but if youre looking to upgrade for big ponies, well you know the rest.
