i think it specs out to be 1.5 qt.. what about putting 2 qts in..cover the bearings better, keep them cooler..
Pre-'75 Alfa designed just about everything "right", and you can't fairly compare the technology of that day with parts much (as in decades) newer. e.g. install headers and a big exhaust on a '74 Spider, and you'll get worse performance and longevity, not better. Take off the Spica air filter and install something else, again, worse performance. Use a newer synthetic oil in the gearbox, guess what? And on and on . . .just a thought...( shure, those alfa engineers didn't know what they were doing...) so all the ' mod's ' that people here have done, are for naught?mega squirt, turbos, lighting gears, other igntion system that even part stores sell to us?bigger cams?..
