Hello all,

I recently bought a set of King XP main bearings for my small block stroker motor I'm building. Upon getting them I realized there not a full groove bearing. We've always run full groove bearings in our race small blocks with the theory they oiled better. What's every one running for there high horsepower, higher rpm engines? What are your guys thoughts on full groove, 3/4 groove, and 1/2 groove bearings?

Thanks, Mark
