Ford Racing M-6261-D351 Roller Camshaft Bearings for 351 Ford Engines

Looking for a really trick way to drop a bunch of friction in your Ford engine? Naturally, Ford has the answer. Their roller cam bearings will do the trick. They're ultra-low-friction needle roller types, and they require so little lubrication that you can actually block off the stock cam oiling holes. Normal 'splash' in the crankcase will get the bearings all the oil they require. This reduces both oil aeration and windage losses. Block machining and an SAE 8620 steel camshaft are required.
