Do you want to start a GY6 engine build from scratch? This is the best route to start with! This is our ProBld GY6 long case B Block. A B block has 57mm stud spacing unlike the standard GY6 54mm stud spacing A Block. Not to mention these are made in Taiwan not China, the quality is way way better! These cases come ready to go to accept up to 70mm cylinders (232cc friendly). No case boring, these are machines out to the max. These engine cases are also equipped with oil cooler ports. No need for the drain plug style oil cooler adaptor. These cases are complete raw with no bearings or bushings. Perfect to get powder coated. A gasket kit is included.
