Anyone made a switch from an ECM controlled motor to a non emmission one? What I'd like to do is Clean up the engine compartment by removing emmissions equipment. There must be a million ugly vaccum tubes strewn out around my engine. Ugh. What would be involved in the swap? A non computer controlled HEI dist? A new carb? I want to know what I'm looking at. My truck runs clean enough that I can pass with cats alone since that's all they check for.
