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?..

I don't get the performance mods with sump capacity comparison. :confused:

Bearings sitting in more oil will increase the rolling friction and therefore increase the temperature. Not to mention possible aeration of the oil and foaming issues.

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 . . .

Once the government starting getting involved, of course, things changed for the worse, and that's why we can't buy new Spider's anymore

Yes, I do have a breakerless ignition on my '74, but the only real performance advantage is reliability and much less maintenance. Other than that, it's just like it came from the factory.

As for the diff, the lip seals in the axle tubes are inboard of the hub bearings anyhow so diff oil does not touch the bearings unless your seals are bad in which the diff oil will soak your bearings, emergency brake shoes and eventually the insides of your wheels...
