But im looking to buy another cheap truck daily driver and found a 1969 4x4 3/4 350 4 speed for 950$ rough but runs and everything works.i was just wondering what kinda gas milage these old trucks get. my dakota gets about 14 now so anything around there would be alright with me. also do you think thier would be a difference between 3/4ton and 1/2ton. | | | | | Joined: Jan 2008 Posts: 4,962 'Bolter | | 'Bolter Joined: Jan 2008 Posts: 4,962 | If your getting 14 now, you'll be lucky to get 10 with a 3/4 ton. | | | | | Joined: Oct 2006 Posts: 4,983 Master Gabster | | Master Gabster Joined: Oct 2006 Posts: 4,983 | Several things go against mileage here: 3/4 ton - 4x4 and an old loose engine. You would be lucky to get 14 mpg.

| | | | | Joined: Nov 2002 Posts: 1,002 Shop Shark | | Shop Shark Joined: Nov 2002 Posts: 1,002 | I have a 68 3/4 ton 2WD, it had a 327, lucky to get 9 mpg, if I stayed under 2500 RPM. It had 116k on it when I got it and the cam was bad, I replaced the cam before I drove it. It also had 4.56 gears in the rear. I know have a 350 out of a 72 4X4, had to replace the cam, some of the lobes were worn 25%. I now have 3.73 gears a if I keep it under 2.5k I'll get maybe 12 mpg. Late 60s and early 70s Chevy cams are a known problem. Offer him less if it's decent.

I don't own a vehicle that isn't old enough to drink.

Runs beautiful on leaner jets since it's parked at 8500 feet. 13 miles to the gallon and no more. | | | | | Joined: Feb 2006 Posts: 549 Shop Shark | | Shop Shark Joined: Feb 2006 Posts: 549 | 3/4 ton - 4x4 and a loose engine, you should get 15 easy. 7 mpg in town and 8 on the highway - that's 15 right?  | | | | | Joined: Sep 2006 Posts: 49 Shop Shark | | Shop Shark Joined: Sep 2006 Posts: 49 | I have a '64 K10 'Burb, 350, with Holley 4 barrel, 4 speed and 373.
At a constant 60 mph on the highway I get 13.5. Around town ? mpg.
Too many cold starts to know for sure. Probably about 8-10. | | | | | Joined: Feb 2008 Posts: 207 Wrench Fetcher | | Wrench Fetcher Joined: Feb 2008 Posts: 207 | i have a '73 C20, 400 small block edlbrock 600CFM carb and intake, 350 trans,4.11 rear. it gets 11 pulling a empty 18 foot flatbed and about 8 carrying 13,000LBS of wood with that trailer. it probably would have got better if there weren't so many hills. but that engine only has 3-4000 miles on it. | | |
