89-K ON THIS ENGINE THAT I WENT TO SEE RUN BEFORE IT WAS PULLED... EXCELLENT RUNNING ENGINE.... IT RAN SMOOTH AND QUIET... NO LEAKS, CLEAN ENGINE... this is NOT your pick and pull engine.... THIS ENGINE FITS THE 2010 THRU 2015 TITAN AND ARMADA WITH 4TH DIGIT IS (B) FOR FLEX FUEL TYPE... if you have a 2010 thru 2015 clean body titan you want to sell with a bad motor or trans,.... lets me know what you want for your truck..... thank for looking
