The Stovebolt Site Forums The Shop Area Engine Shop Front and rear end for my 65 K10

Once my truck is up and running, (hopefully next week :), I expect I will want to maintain decent highway speeds. Any of the fellow Bolters know a good front/rear end combo that will get me to 80+mph, and still allow me to keep it a 4x4? That maybe include some upgrades, like disk brakes and such? Won't be an immediate need, just would like some time to do the research and pricing. (READ AS "Begging and pleading with the wife!" ) Any help is greatly appreciated. (With the truck, NOT the Wife! ) Thanks.

your going to need at least 3:73 gears my 61 had 4:10 stock their getting harder to find .make sure your knuckle joint's are in good shape if you want to run that fast a higher gear would be nicer ,depends on what is available .i don't know if some body has a ratio computer ?

Brand new to this mechanical thing. Lovin it, but definitely don't have the experience many have here. But of course thats why most of us are here!

Really no need to swap axles. A '65 will have a Spicer/Dana 44F up front, and a GM 12 bolt Truck rearend. New gears are readily available in most ratios from 3.08 up into the 4.88 ranges. A 3.55-3.73 would be very good, depending on what size tires you run. About the only reason I can see to swap the fron axle would be to get open knuckles (stronger design) and disk brakes. You'll want to look for a '71-'76 4x4 Chevy to get that axle, most '77-'87 GMs used a 10 bolt up front. Both would work, though.

The tire size is 33x12.5x15. Will start checking this out. Don't suppose there is a Saga or tech tip on this particular swap? With ? If not, I will just have to work it out. Thanks for the info.
