Thank you men. All great input for me.
Although the distributor is a new HEI and the carb had been rebuilt by a pro, things can still go wrong with them. Never did a compression check either. 66K on the odometer.
Interesting point on timing: The harmonic balancer shifted it's mark and the shop had to go by "ear" to time it. I have the replacement balancer here, along with the tools to pull & install it, as well as all the gaskets, and even a replacement timing chain/gear set. That timing may very well be the culprit. Just waiting for cooler weather to do it. This town is burnin' up right now. Really!
Thanks again.

If your exhaust pipes are black, it isn't timing but raw gas being dumped down the engine.
Another issue that can destroy gas mileage is to have the gasoline return line break and literally pump gas out on the ground. However, that won't make your pipes black.

Pay more/get less/be happy......"We're the EPA--and we've come to help"...... 10 years ago I filled up with gas--normally get 25 mpg in the mini-van.....It got 31mpg---I had my daughter who was with me verify the numbers---makes you wonder what the tech did who was mixing the fuel at the refinery that day---maybe he didn't "thin" the main ingredient....

6.2 MPG would not be "normal".
This needs to be addressed, as beside the hit to your wallet, I suspect raw fuel not being burned, therefore dumping it down into the crankcase.
This fuel dilutes the oil, and then the oil looses its lubricating qualities..eventually even a bigger hit to your wallet, with abnormal engine wear.
Good luck, in getting this resolved.

I don't think it was the EPA that was responsible for ethanol...I think it was the corn growing barons who already get millions from the gov who gave lots to congressmen to have it added to our tanks and of course as a bi-product of their corn, the refinery's who make millions from it helping with the donations.
