First fuel "fill" since I converted over to the WW3-275 carb and Dutra duals with 2 1/4" plumbing

I calculate 15 MPG after burning 8.875 gallons.

Keep in mind I always have my foot on it. That will pass

Maybe see what.. ... 17.. ....with a lighter touch.

What gears and transmission do you have? Is that city or highway or mixed?

904 auto and I'm assuming stock (3.23) rear end. (Someone will correct me here if I am wrong about that)

Guess I should spend some time to calculate it at some point to be sure.

City and highway. Can't keep it under 70-75 on the freeway. That too will pass.

Again, I've had a heavy foot since the conversion.

That is what my Stromberg did exactly. It did give it more power. I went back to the BBD which gave me 22 MPG all the time. The car was my daily driver at the time, and I put tons of miles on it, so it was important to get that 50% improvement. But, the Stromberg made it feel like a V-8.

Have you recurved your distributor at all. If not, I think if you play with your timing curve you might do better. Take a look at Aggressive Ted's set up under the FAQ thread of the Engine section.
