Todd's right, pretty much everyone you will talk to will tell you that on our engines, it sucks.
I asked the same question some time ago, and I only found one that suggested it, but only becouse "they make the same sound as turbo's, thats cool.":huh:
What year was it then that the spacer was the eliminator and larger ?? was it 85 I am thinking of ?? with speed density or the later 89 with the MAF ???
Todd, the egr spacer was eliminated on the 302 t-birds and '94-'95 302 stang. They mounted the egr valve right on the upper plenum after the TB. The '88 stang in CA. was MAF. The rest of us were speed density until '89..
