x2 on those who said gears. being a 2wd i'd guess either 3.0 or 3.42 gears. go with 3.73. in the glovebox, look for GT4 rpo code for 3.73. not too hard to find in a pull a part

What year? my 98 has the 305 and it has enough power, but not an excess. Also 19-20 mpg? I.m sorry but i gotta see proof on that lol my best is 14mpg highway. I do have 4x4 and a ext cab though.I have a Chevy truck with the 305 engine and it is no dog as many here say. Most of everything on it is stock and the truck has over 133,000 miles on it. It gets about 18 to 20 mpg depending on how hard I push it. I occasionally haul more than 2300 pound loads from the pier over 80 miles one way. There are some drawn out hills that get steeper as I get near the top of the hill. The truck seems to always have no problem doing it, so I say it is not a dog at all. My guess is that something is not tuned right with the 305 engines that act like dogs.
There is one thing that my truck has which is not stock though. My air cleaner is a combination of two K&N filters. The regular base ring filter and a top (cap) filter. There are no metal sides or metal cap as the original filter has. I cut the sides off of the original base. This set up could be why the engine seems sweet to me. It definitely does not sound or act like a dog when I push it.
I also have a 2000 Silverado with the 6.0 L engine, so I know how a strong engine is supposed to feel.
There's no way you only get 14 mpg highway in a 5.0 lol, I would guess 18 or so. Heck, even my K3500 CCLB 5.7 obtained 16.8 mpg once, given it was onflat roads at 5600 ft elevation burning Supreme fuel, but still.What year? my 98 has the 305 and it has enough power, but not an excess.

the best I've ever gotten highway is close to 15, and I burn 87. I dunno man maybe its the gearing I got 3.73. I have the logs to prove the mileage though. I recently had a trip whereIi calculated my mileage and I got an incredible 14.8, all highway. everything I've heard about the 5.0s from other people has pretty much confirmed my case. I think they're fine motors just kind of are middle of the road.There's no way you only get 14 mpg highway in a 5.0 lol, I would guess 18 or so.

Good point, you can use radar signs in school zones for speedometers and mile markers on highways for odometers, or drive 60MPH and time 1 mile (s/b 60 seconds). My Dakota Digital dash has the capability to calibrate by time or distance. When I did the distance, I hit the start button and when I got to the next mile marker I hit it again. That calibrated both. I know this is different than OEM dashes but, as a check you should be able to use the road side tools to know how close you are.How many of you who are calculating mileage have calibrated your speedometer? The other question is how accurately does the odometer track with the speedometer?
