Rob Posted April 7, 2011 Share Posted April 7, 2011 Today I received my new 8VBB injection pump, (never installed on a truck) and nozzles back from the fuel shop. I had the pump recalibrated from the ENDT865 engine to the 1974 ENDT866 engine +15% for a little extra "umph" if needed. The engine runs pretty good now with a lazy, slobbering injector, (sorta like me) and should smooth out nicely once this stuff is installed. I've never had the induction system apart on the truck so don't know if turbo is going to need freshed or not, but suppose that is next. Also planning to swap the SQHD 4.11 rears for the 3.70's already acquired. The 10 speed direct should give a good road speed on 11RX22.5 tires.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.
