Default Cleveland vs Windsor

The Cleveland has 2 3/4" mains which allows it to turn higher rpms. The Windsor has 3" mains which will see 20% more fiction than the 2 3/4" main. The Cleveland had bad oiling problems. The 4 v heads are to large for street. The best of both worlds is a Windsor block with 2 3/4" mains ( spacer kit from Ford or a World Class bock). 7500 rpms and no oiling problems. There is a great selection of aluminum heads for the Windsor but not the Cleveland. They manufactured the Cleveland from 1970 to 1974. The Windsor from 1969 to 1996. The cheaper of the two would be the Windsor.
