What would be the longevity of a old school engine, say a 327 chevy, built to the tighter tolerances of todays fuel injected engines, with a carb and running a lighter weight oil like 5W30?

That carburetor is the problem. Always heard them described as a poorly regulated fuel leak into an engine.

cost to build is the same for a 265 up to a 406. why would you build a 327 unless it's for class purposes or a numbers matching deal?

Superior machining and running the engine at 198° is the reason the OEM today lasts 150,000 plus miles. Back in the '70's an engine was ready for overhaul at 80K. Today the OEM uses superior machines and runs engines at 198°. Personally I feel the temperature is the number one single reason cars run so much longer these days. But........if the machining was not updated, the improvement with temp wouldn't hold water.
