Sold our Rebuilt Detroit Diesel 12.7L DDEC IV High Performance engine today. Customer brought his A game with the blocking! He’s installing it in his late 90’s Freightliner Argosy, removing the 12.7L in it that has 1.1 million miles and wicked blow-by. Customer didn’t need the PDI Exhaust Manifold and Turbo, he’s swapping his valve cover, ECM and all external components off his core. Thank you John for the business, cant wait to see it installed!
