4.64 rears with 43.4" tall tires with a .78 overdrive in 12 gear at 2100 RPM you will be at 74.95 MPH

 

1800RPM = 65mph

I was wondering what the top speed would be on 12 speed (1070B) with 4.64 gearing? I believe truck has 11R 24.5 on it. Thanks 

Personally,i would continue my search for a more suitable truck for this type endeavor,i mean when's the last time you saw another General? parts availability has to factor in,replacement parts for a GMC general specific are damn near non-existant anymore. What are the specs.? is this truck set up for this type work,or is it a converted OTR tractor? IE: Air-ride,aluminum frame,trans.,engine etc. Even in your comfort zone(price/agewise) my thinking is something a little more current may be a better choice, although it is hard for me to recommend anything but a Mack, IH does come to mind as far as parts availabilty/service, even a heavier duty L-series Ford in my opinion would be a better choice as they literally made thousands of them! while a General is a fairly rare bird these days! I am a firn believer in the right truck for the job,and keep in mind this is just my considered opinion,there may be others that disagree. Hope this is of some help!..................Mark

You hit the nail on the head on the rarity of Generals on the road these days! The truck has an 18 front 46 rears, 13 speed and a 400 cat. They were popular in my area ( New England)years ago, Kelton Motors sold many, but parts are a worry for sure. Like I said It's not my first choice but it's got a newer loader and log body on it.

Hello, I have been reading topics on this site for the past year and have learned a lot. Theres some very knowledgeable people posting. I need to buy a tri axle log truck to compliment my logging business and I'm going to look at an '86 GMC 5 Star General later in the week. What are people's general perceptions concerning these trucks? Good points/Bad points? Noteworthy things to look for (other than basic stuff)? My wallet limits me to the mid 80's to early 90's era. My first choice would be an R or Superliner with a 350/12 speed, 18/50K but have not spotted one yet. Responses greatly appreciated.

Thanks,

John
