Brian B.:
Oh there were a few full throttle blasts "around town". All in the name of scientific inquiry of course!

Cliff Ruggles:
That's expected, don't think I've ever ran a tank of gas thru the Ventura where it didn't get "cleaned out" half a dozen times....or more!....

Glutenfreecarbs:
I'd probably be above 20 MPG if I stayed out of the secondaries... And I'll admit I get right down to 12 MPG during summertime city driving; running the A/C compressor, idling around jobsites, "hurry-up-and-stop" traffic in suburbia, waiting in line at the brew-through, etc...

73ss:
I'd guestimate 14~15 with my old 454 setup on the expressway, In OD, With convertor locked up. Like many of you, It's a challenge to stay out of the secondaries from time to time. Speedo reads 7 slow so couldn't get an exact figure.

Greasy Harley:
My '79 K10 has a 350, sm465, 3.73:1 gears and 32/11.50/R15's.
It gets 10mpg ...it can get 12 (just not the way I drive it) ;)
