Rear End Help
 

I have a 1970 c30 chevy one ton truck and I am trying to figure out what rear end is under it. I have been looking around to try to find information on it but everything Ive found shows one with a drop out 3rd member. Mine does not have this and looks more like a dana. Was a dana ever offered in this year model truck? I know it has 4:56 gears and the truck was an original v8 with chevy 4spd.

Any help is much appreciated!

Thank you

There were Eaton reare ends put under these trucks too. No drop out 3rd member, and they have a rear pan with 10 bolts holding on the cover. Post up a pic.

this is the only picture I have on my computer

That looks a lot like a 14 bolt FF that did not come in these trucks until around 1976.

So it's possible it was swapped in. If so, it's a damn good rear end (bomb proof), and parts are easy to find but can get pricey.

Yup, looks like a 14bolt to me too. Not original to the truck, but a nice upgrade.

Here is another picture of the rear end, but it sounds like its a 14 bolt ff and if it is what are the estimated hp and torque limits of it?

Bulletproof.....

Even a Big Block 496 at around 700 horses?
