Every MFG. was struggling with emissions and everybody had 500' of Vacuum line in every car. My new 83 GMC 2.8l V-6 T-15 had an amazing 115 h.p. to go with 500' of vacuum line.
Best move I made on all my CJ's was to pull the factory 2 barrel and install a 2 barrel webber carb.
Always carried WD40 to spray out the distributor cap after a fast water crossing too.
But lord no CEL, no ECM and no O2 sensors sure was freaking nice!!!!!!
