TB Spacer Recomendations

Does anyone have a TB spacer on their truck? Can anyone recomend a brand to go with? I have a 94 4.3 Vortec with CPI.

Thanks

I just was wondering. Are you planning on converting your CPI injectors system to a throttle body injector? If you are the spacers really don't make no sense. I mean the TB injectors are positioned to spray they fuel at a PSI that will induce fuel into your engine. Now you move the injector further away from the PSI calculated point. The fuel introduction takes longer to reach you combustion chambers. If your using a regular 2 or 4 barrel carb. You then would benefit from it. Because your able to adjust your air and fuel mixture. I feel you would be just wasting your money on a spacer.

my mistake I had a brain fart don't mind me.
