Holley's science vs Edelbrock simplicity?

I've been running an early1970s 750DP since about year 2000. After the initial tune, I've just been driving and driving and driving, to the tune of over 100,000 miles. Carb is sorta worn out by now........ but it's like the Energizer Bunny.

Correct! After the initial tune, they just keep going and going.... LOL. ... LOL.
