Chevy 3.5/3.9 v6 swap question (Page 1/1) Cajun MAY 16, 11:02 AM For those of you who have done or in the process of doing a Chevy 3.5/3.9 v6 swap, how did you address the EVAP (Evaporative Emission System)? I have not seen any mention of the EVAP in posted 3.5/3.9 v6 swaps. Or did you just eliminate the EVAP? I am trying to finish up my wiring harness and that information would be good to know how others have addressed the EVAP. I have also posted this question in "General Section" Thanks in advance for any feedback.
