I would never want to run a short block that was built and sat around for 10 years. Piston rings do not like sitting in one place for that long.
You made a wise choice in passing on it for more reason other than the cost. It would need to have been torn apart anyway before I would have ever...
I changed the sentence to read, " As far as a Dana 70 is concerned he takes the carriers out to use the guts in Dana 60's and saves a few sets of gears, but rarely do you ever need to replace a 70 gear set."

You get a semi floater or a full floater depending on the GVW rating of the truck. Light duty 3/4 tons can come with either depended on how they were ordered. You also have to be careful when using pickup and van rear ends because a lot of the lighter duty 3/4 ton trucks had Dana 61's in them to...
Unless you're using a Dana 61 you're not going to get anything taller than a 3.54 ratio for a Dana 60.

As far as the two gear set the OP asked about I'll say this. Going from a 2.94 that you're used to driving to a 3.55 is going to feel like you
need another gear. It all sounds good, but driving a 3.55 geared car without overdrive is absolute a borderline deal. If your 440 can't spin the
tires...
