CARB SPACERS

You need to try every spacer you can get your hands on.
I run a two inch phenolic(plastic?) spacer. A two inch spacer puts the bottom of my air cleaner at hood level. The air filter is entirely in the scoop. One of the two days I spent tuning the engine instead of the suspension I played with spacers.

My car likes the four hole spacer, over .100 difference!
A four hole spacer can improve the signal to the carb...
I have a two inch phenolic super sucker I want to try, soon!
