My old Ferrari GT 250 had a massive three row chain on the cams. That engine and car was built to run at LeMans. Roller tipped rockers, 4 sets of points in two distributors each set running three cylinders designed with smooth long ramps on the point cam for sustained high rpm, massive radiator, massive aluminum brakes, aluminum everything almost...it held 12 Quarts of oil with 3 liters....40 gallon fuel tank and on and on. It had a steel body but had aluminum floor, fire wal, transmission hump and aluminum hood and trunk. The tubular frame ran under the transmission so the hump was removable and the tranny came out through the passenger compartment. I had that car all apart and back together again.
