I'm clueless on how to do this? If you've done this mod how long did it take? Did you feel a gain? Thanks for your time, if needed the car is a 1994 lt1 t/a.

 

Before you start this easy little project you will need a piece of 3/8 inch tubing, brass works well. Also, you will need some sort of plug or cap to cover the elbows on your throttle body. I used rubber caps found in any parts store, they should be 3/8-1/2 inch in diameter. Now lets get down to business newbie,
Some say there is a noticable gain, I say its . All this "mod" is doing is preventing coolent from entering your throttle body, possibly raising the temp and allowing for better atomization of the fuel mixture... Whatever! Anyways, it is SUPER easy, you will see an elbow on either side of your throttle body with a coolent hose attached to them. Remove both hoses and use the piece of pipe i descried previously to patch them together affectively eliminating the coolent flow to the throttle body. You are left with two elbows on your TB, simply use those black rubber caps that I recomended to cap them up. The final step involves bleeding your coolent system. It is very simple, do not let the name scare you. You must start your car, allow it to get to opperating temp, then use a straight slot screw driver to open the bleeding valves on the hard rail near your radiator. There are two, and if you do not do this procedure after you do your TB bypass, your car will over heat and spill coolent onto your garage floor, possibly soaking your jack, and spilling into your tool box. (Just a guess) OH and be carefull not to apply to much force to the bleed screws, as the break very easily, (certainly do not use a power screw driver) you may break one and need to borrow one from a buddy named Adam. (just guessing again)

Good Luck, its easy, and may or may not show a gain.
