A black LT5 is a lot like a white elephant. Very rare and extremely powerful. When George Bonafide located this black, MerCruiser-prepared LT5, he knew that more than just black wrinkle finish separated it from the original engine in his 90 ZR-1. The history of this engine includes names of speed merchants who have set records with other ZR-1s, so we knew there was definitely something special about this engine.
George purchased two engines, which were reportedly part of Tommy Morrisons collection. Follow along with us as we show what it takes to remove and replace an LT5.
