I had a ,47 Buick Special, with the 'sparrow strainer' Humongous seating room. Smooooth enigine with not much power. Three on a stick.
However, the ohv straight eight rocker arms often had the oil line clog up and the rockers wore quickly. Mine was noisy.
55 56 57 Oldsmobile V-8s had the lack of oil situation also. When I rebuilt the 350 V-8 in my Chevy pickup I put in a T R W Racing oil pump and adjustable rocker arms removing the hydrastic lifters. Lets just say the oil stains were still on the garage ceiling after we were done adjusting things. RIDE SAFE.
