This is one of our latest 427 LS Next based Stage III Power Adder Long Block built for Mr. Pawlo Czerepaniak and his dad Dmytro. What the engine will be going in is being kept under wraps for now, but will be using a ProCharger and a few other extra touches. As with all Shafiroff Racing Long Blocks, every build is dyno tested with our own intake manifold and carbureter. Even with it's lower compression and custom blower camshaft, the power easily reaches 660 HP!
