Back to the trottle body spacers. Don't waste your money. GM spent millions designing it into your engine, its called Vortec. All 4.3L engines are vortec's.

RE: Throttle Body Spacer
i put a tbs on my 92 350 tpi fullsize and i noticed a big difference but all i ahve heard is to stay away from tbs on these cause they dont even mix the fuel up there... and the spiral is then useless cause it supposed to create a better mixture of fuel and air.. and if only air is being pulled through it it makes it completely useless

One of our fearless mods summed it up earlier this month. (swartkk)

The way a TB spacer works is by increasing the volume of air between the throttle blade and the valves. A TB spacer will effectively move the torque curve lower in the rpm band. It will do this at the expense of higher RPM torque, but if you think about how much time you spend at 3500+rpm...

Throttle Body Spacers give more time to mix before it burns up in the engine. i'm plannin on gettin it when i get back to work come summer.

That is only true for TBI or carb motors. With the CPI or SCFI motors, the fuel is injected directly ahead of the intake valve. The length of the intake path before the injector has nothing to do with the fuel/air mixture.
