New to the dually scene!!!

Yeah yeah... If mine were a gas engine, I would walk back to my parts dept and pick up the ZZ572 <img src="{SMILIES_PATH}/icon_surprised.gif" alt=":o" title="Surprised" /> , we keep those in stock!!!!lol

As far as cutting to the chase, If this was easy everybody would do it....I like a lil challenge, besides I think I have done my part repin GM.

Aw well geez man if it's an issue of not knowing where to stash some of those ZZ572's, I have two spots available, you'll let me slide on that 26K right?

I have a pair of 94's that wouldn't mind, and I swerz I won't tell anybody where those junky old engines came from.

we had a 95 chevy 2500 service truck at my house that my dad blew up a year or so ago...it has a brand new 4l80 trans in it with maybe 1000 miles on it...then he run it hot and blew it up and said he wasnt spending any more money on that piece of junk...im thinkin about usin the trans in my 85 but my question is can i use the rear end out from under it as a shorter one like a C&amp;C one(hell it might be classified as a C&amp;C) im not sure about all that....its the same gear ratio as my dually so maybe i can use it...here a few pics


notice the custom chain exhaust hanger

You can use that rear but you'll have to read up on what it would take to convert it to duals, I can't tell from the pic if it's a full floater or semi floater, the 8 lug 2500's came both ways in those years. Quickest way to ID would be pop a hubcap off and see if it has the big hub of a full floater, or even quicker look at the area around the pinion yoke - if the &quot;collar&quot; around it is bolted onto the case, it's a full floater.

You'll most likely have to relocate the spring perches and shock mounts because there's not a lot in common between the body styles as far as that goes.

That rear is not as narrow as a C&amp;C dually. Now I'm oversimplifying the measurements here but this is in a nutshell how it plays out:

On a non-dually the rear tires and front tires are pretty much in line with each other (the rear is slightly narrower but not by much.)

On a regular dually, the inside rears are in the same position, lining up with the front tires, while the outside rears of course stick out.

On a C&amp;C dually, the inside rears sit closer to the frame and the gap between the inside and outside duals is what lines up with the front tires, if that makes sense.

As far as using the '95 4L80E transmission in your '85, you'll have to jump through some hoops; either you'll need a standalone controller (they cost about a grand, sometimes can be found cheaper) and a harness, or convert it to manual shift valve body. Or of course if you convert your '85 over to EFI and run a later model engine just bring over the computer, harness, and everything. Just beware that '95 model of the transmission is a one year only unit (details: PWM on the TCC) so you'll want to keep that truck's PCM with it.

damn i didnt know that trans controller was that expensive....its already dark and that truck is down in teh field so ill check out the hub tomorrow

there are a couple of controllers for the 4 l 80 i have seen another one that makes it a full manual thats quite a bit cheaper

if the engine in the donor is a gas one and you know electronics a bit you might be able to use the original controller for it
megasquirt is the linux under the aftermarket ecu and last wat i heared about it they where working on having it operate automatics as whell
it can be ordered as a kit and build at home or bought ready made at a mush lower cost than the stand alone boxes they sell for the 4l80e
the software to program it is free too and there 2 big forums that discuss the possibilities of the ecu adaptations and programming it

got the dually in the shop and ripped apart last night....gotta love trucks that come from the beach...rusty bolts suck ass....but anyway progress is coming along pretty smoothly....few questions...how tall do the bag cups need to be for stock arms with the 3 inch drop spindals...also we pulled the front springs out today to see how far from frame it is once the front crossmember hits and its only about 1/2 inch from the frame...might z it a couple of inches just to keep the control arms off the dirt but other than that its going good...prolly pull the cab and drivetrain this week and start on the bodydrop...here s a teaser pic

Nice looking Square.

Bag cups are normally 6&quot; tall but most of the time end up getting trimmed to your application.

Nice!
