So back when the car was new there wasn't much concern about Babbitt doing higher compression ratios, oiling center main, splash lubed rods--- and 100 mph---- it does say that babbited brass insert for only upper center main can be improvement
100 mph is well over 3000 rpm----- to does say stock rotor comes apart over 85 mph
