Sounds like you made some good progress and got real lucky with the dist. It's one of the MP distributors that has the Mallory type advance which sure makes it nice. Only thing is I would have expected it to like lighter springs than what you used but if it's running good leave it be. Check your mileage like Cannucky said. That's the only accurate way to tell what it's really doing. What the fuel gauge says isn't accurate usually. The one in my Cuda will go about 150 miles before it drops to 1/2 tank then it drops from 1/2 tank to empty in about 80 miles. Fuel gauges on our old stuff generally isn't linear so that's why the only accurate test is like Steve said
