I know it's been talked about before. But, I just thought I'd start a thread to see what people are getting with what combo.

Today, I got 10.2 mpg's all freeway - C20 - 350 w/ Powerglide .. DOH!!!!

I got 10.5 mpg with my 65 c10 on the freeway that with a stock 2 barrel, 283-700r4, and 3.73 gears.

Havn't check it since i got the tbi.

I get around 12mpg as long as I keep it under 65, that's with 2x450 holleys and 3:73's. If I drive like I want to I get about 6...

Just figured it out last weekend - 12.75MPG on the freeway at 60 MPH. I run a 400 small block in my truck with a th350, 4.10 gears and a 27 inch tall tire.

...don't care...I rate mine on "fun per mile" 350/350 -3:73 ratio 15 " wheels.....

Eliasj123 · 04-02-2007, 02:55 PM

LOL.. I hear you..

I'm starting to care because I'm starting to drive my '64 almost everyday.

My I should dust off my '55 sedan. At least the gas gauge doesn't work right and I wouldn't be able to figure out the MPG's

Sometimes denial is the best policy..

These trucks are as aerodynamic as barn doors.... around town I get 17.5. During a recent 800 mile parts run to Salt Lake City I got around 14..... 80-85 mph the whole way..... 2003 5.3/4L60E

My 64 C10 w/ 230L6 got 16 mpg empty at about 55 mpg freeway. MPG dropped fast when a load was added. Poor little engine had to work so hard.

My dad has some mid-90's Chev PU with 350, not sure of details, but we did talk about MPG once, he got 20 MPG on freway when he first got it. Over the years it dropped to about 17. (Needs a tune up?)

My same 64 C10 now has a 350, don't know the MPG, the speedo/odometer has worked for a decade.

Just did a recent round trip of 238 miles through towns but mostly 60-70 mph and got 16.8 mpg with my 66 longbed fleetside. The combo is a warmed over 355 SBC with an RV cam and a 650 Holley mated to a S10 5 speed with a .73 5th gear and 3.73 in the back with a 29" tire. I was happy!

My gauges don't work.

Eliasj123 · 04-11-2007, 12:59 PM

I'm jealous of you guys who get 14mpgs +...

I would drive my 64 everywhere if I got 15 or 16 mpg...
