TB spacer

Anyone run one of these on ther TBI truck. What was the gains and was it worth it. I see that it helps alot on the new 4.3 but not sure if it will be worth it for my rig. Thanks in advance.

I put a 1 inch phenelic one on my 91 4.3 and it seemed to help with throttle response.As far as mileage goes it`s hard to tell with the weather going cold warm cold.

Re: TB spacer

i put a home made one on my 89. my truck was running so crappy so i couldn't even tell if it helped or not. i actually made 2 1" ones, thinking i could put both of them on there, but the throttle cable wasn't long enough.... probably a good thing anyhow. to make it all i did was trace the pattern off of the gasket that goes between the tbi and the intake manifold onto a block of aluminum and had it cut out... pretty simple.

Re: TB spacer

You're gonna sacrifice most of your low-end power if you do even a 1" TBI spacer. The factory intake has a pretty good rise built into it, so unless you have a top-end cam and engine built for high RPM's I'd stray away from it. Not very economical at $70 for a chunk of aluminum and some gaskets IMHO. Save up for some JBA headers instead!

Re: TB spacer

I don`t agree with that if anything i gained low end power.
