GT40 Intake manifold question?

Levon · February 22nd, 2008, 12:16 AM

I installed a gt40 u/l manifold on my 95, manifold was from a 93 never used, but I was told all I have to do is add the elbow to complete the install. Never the less I added the spacer between the upper and lower and the EGR line became to short for the fitting ends. Is there a after market part that will cure the problem. or will I have to makeshift a line.

I did away with the manifold spacer but, I'm wanting to add it to gain some more horses.

JFYI the spacer will net you next to nothing as far hp. Most people run them just for clearence issues.

i think the spacer is more for TQ. But i used mine for clearance. My throttle linkage on the t-body was hitting the valve covers without the spacer.

Let's not forget about heat transfer--it does make a little difference there.

It all depends on what then engine wants. Sometimes spacers gain horsepower, sometimes they lose horsepower and sometimes they don't gain or lose. Every engine is different.
