My buddy does mechanic work.. He put an A Zone $5,800 Hemmi crate engine in a Charger for a guy who insisted he wanted a CRATE ENGINE installed. At 350 miles the engine got noisy (rattling knock). Co that furnished the Crate Engine sent out Tech. They agreed to a another engine, Labor for the swap, pay all reasonable expenses (oil, filter,.....) To be furnished through A Z. He went to pick up the engine. The long time Parts Guy gave him a new engine, new name brand filter and a 5 Qt Jug of PENZ OIL FULL STHETIC. Thats for a new For a new replacement Crate Engine. Your thoughts.
