Another driveshaft question

[Layne]

Yep! What everyone else stated! I couldn't remember it, but I was phasing it. Thanks Vile

I see I really opened a can of worms with this one. But you guy's gave me some food for thought. Especially on things like drive shaft angles and RPMs. I my mind the longer  one piece shaft would have less angle than the back end of a two piece shaft. I also wonder how much RPM difference exists between a 12  bolt rear end with a  8 7/8" ring gear and 15" tires vs. a 14 bolt rear end with a 9 1/2" ring gear and 16.5 tires? I have 3:73 gears so I guess it does turn pretty fast.
  My truck is a "retired" work truck and now pretty much leads a "life of leisure" if that's possible for a truck. LOL! I drive it to work everday but I don't tow anything and the biggest thing I've hauled so far was a Powerwheels Mustang for my Grand Daughter's Christmas. I was thinking I could keep the two piece and reinstall it if I ever buy a travel trailer or big  boat something.
 Thank you for all the input but no one however, answered my original question: Did Chevy build a half ton, long bed with the TH400? Thanks again for all the replies.

I am sure they did but someone might have changed it down the road.  They made both long and short tail shaft TH400.  I have seen both in our trucks.

I do not recall ever seeing a factory half ton long bed or short bed for that matter, with a Turbo 400 from the factory. All have been T350 if they were automatic that I have seen back in those days. From memory, what I remember, half tons got T350 and 3/4 and 1 ton got T400. The 3/4 and 1 ton got Turbo 400 regardless of engine size, so even if it were a small block. But if you got a Big block in half ton, it was a T400. I do not recall ever working on a factory big block half ton truck in this era, but I am sure they exist. But I think that is the only way you'd get a T400 in a half ton, is it were a factory big block 1/2 ton.

Lots of these trucks 1/2 ton came with TH400's

[hotrodpc]

Cool, I have never seen one, and I have worked on lots of these trucks. I build automatic transmissions, and yet to build a 400 out of a half ton. Done a few in 3/4 and 1 tons. Done lots of 350's though in half tons. Maybe because 400's last so long could be why. So now that makes me wonder if those 1/2 tons with 400's have a 1 piece or 2 piece shaft. Of my 6 trucks, 4 are half tons and all are 1 piece driveline w/ turbo 350 including the K10 that is a 700r4 w/NP208. That truck does not have a drivetrain in it right now, but I do have the rear driveshaft for it. Both of my 3/4 tons are Turbo 400 and 2 piece shafts. 1 being a factory 454 w full float 14bolt, 1 being a factory 350 with Semi Float 14 bolt.

My 74 C15 came Th400 2 piece
My 80 C10 came Th400 1 piece

Both were long beds

[bobcooter]

Thanks Guy's. I may still try it. If I do I'll let you know. If it fly's into a million pieces like Vile said, I'll let you know that too!

Sounds good Cooter. Anyway you can mount a video cam under the truck? We want to see that carnage as it happens. I say its gonna be fine, no matter which way you choose to go.
