Hi I own a 86 chevy shortbox 2 wheel drivewith a v6, 400trans, 3:42 posi gear it is an Arizona truck so it is rust free. I live in Minnesota and wow the frame still has the original paint on it and not a spot of rust on it. I am in the process of installing a 350 in it but the original V6 has so many emissions on it that I am a little confused on the wiring if it would be ok to not use the emissions wiriing and it would run ok or if I need anew wiring harness. I amrunning emissions wxemt so I do not need it, but anyones help would be appreciated Thank you
