Truck gets about 16 mpg mixed driving. Now I would buy a gas truck if I was in the market though. This choice is to give good performance for the expected use. I was just curious if it was actually possible to get 16 mpg out of a 350, because if it was, it might be worth swapping vehicles. I don't think I ever checked the mileage on a longer road trip because I rarely took it on one. I had a 1985 Chevy half ton with the original 350 in it. Higher numerical ratio mean greater engine drag.
I would also prefer a manual, it looks like they're all mainly 4 speeds, so I don't imagine gas mileage is better then the auto's then. Never had a problem with my gearing towing anything I have tried. I considered this a lot, but I've decided it's not really a smart move. It was a pure dog, though, when being asked to pull anything. Also, this truck would be a 4x4, so probably some amount of lift probably no more then 4 inches and sitting on 33's. I'm really much more familiar with boat engines when it comes to American V8's, but I have a 91 chevy suburban 5.
And it is taxing the motor a bit on hills. Might as well just get a cherokee or a chevy that already has a solid axle for no effort and less money. Accelerate to 65 coast to 55 time it. Or maybe if I get some more cash I'll sell the Amigo and get a better vehicle that gets worse mileage. The model size was also part of the name, with 1500 indicating half a ton, 2500 for three-quarters of a ton and 3500 for one ton. Larger tires, more drag and lots of weight in an old v8 truck is not a recipe for mileage.
But i did do a fresh timing chain and four degrees advance on the cam. Truck gets about 16 mpg mixed driving. Q; Why do you think mileage hasn't changed significantly over the last 25 years in full size trucks? I had an 83 Silverado with 305, automatic with lockup converter, and 3. Exceptions trailer packages 4x4 and higher payload systems like 3. .
This is not a partially finished swap that needs tweaking, it has been a daily driver in this configuration foraround the last 30k miles. The th350 and th400 autos suck gas because of no torque converter lock up. Tall gearing all improve part thrilled effiecny but not by a lot unless computerized to run the engine at the ragged edge of precognition with high compression ratios and timed port injection. Ours averages 14 mpg with the use we give it. These were geared to run closer to the torque peak at 65.
Is it really possible to get more then 16 mpg on a regular basis, if well maintained, or is that just a dream? Mine was carbed and all stock except for a free flowing air cleaner and true dual exhaust. Extended cab 4x4 with auto 4 sp. A std short bed carbureted it matters 350 half ton with gearing such that you Turn about 2200 or less rpm in a late 705 to early eights stock truck will be about 16 mpg on the highway at 65 mph. They were designed at the time to give best mpg at 65 by putting the torque peak not at cruising speed but at cruise in 2 nd gear for autos or 3 gear for 4 speed. We'll see, I'm satisfied with the offroadability of the Amigo for now, it gets me everywhere I want to, which I suppose is the most important thing. Might as well just get a cherokee or a chevy that already has a solid axle for no effort and less money.
That is it in a nutshell. In theory you should be able to manage 20-25 mpg. The Silverado can be identified by its chrome grille, which does not appear on other trims. Please ask any and all questions prior to bidding. This is not a partially finished swap that needs tweaking, it has been a daily driver in this configuration foraround the last 30k miles.
Hubs or no hubs on the front axle will affect the mileage, as will the transfer case style - part time or full time 4 wheel drive. I have owned a bunch of them some I wish i still had some i was glad to see go. Th350 did have a lock up option on the last generation. An unlocked torque converter here would help. Everyone thinks I am telling a lie with my mileage but I get a solid 12 mostly country driving. Not sure if that is the same for the 750cfm models. I don't remember what gears it had.
This truck is not a show truck but an incredible driver that you can do some cosmetics over time. It's a blast to drive. At work I get a new truck every 18-24 months I'm currently in a 2011 F350 6. I have done it on a 1983 half ton 4x4 with a manual over drive four speed. Saw 21 mpg Canadian gallon with a tailwind.
Yep or swap a 3-53 detroit, 6. You want good mileage ride a moped. It would cost at least 2 grand, more like 3-4. A m1009 or a civvy version of the same thing would probably be close to your current amount of money in that amigo and might be able to pull 20mpg to boot. Anyone claiming the mid 20's and up to 30 for diesels from a full size truck is either full of shit or there's details missing on driving style.
