i really dont see 30mph being that hard to reach...

i drove my 68 dart to MATS from Phoenix and got 20mpg on the trip there and back...

BUT i have a heavily built motor, .475 lift/246 @ .050 cam,3.91's sure grip, and run 14's...

and i have a 600 HOLLEY DOUBLE PUMPER CARB!

You're right but it has to be a right combination of parts as well you know to achieve it and you really have all the everything to match. If not it just will get the same or worse. Plus the member at /6.org didn't keep records or document everything. Data is what tells the truth.
