It really isn't bad I am averaging 20 to 21 MPG now with the new injectors and I don't drive it all that easy. I am sure straight highway and cruising nicely I could get much better.

 

Nice .. what gears ?

red the sig, but no gears in the sig ... I would assume 4.10's ?

 

Me yes, I am running 4.10's. I was looking at a Disc rear out of a newer Dually to swap in mine and was going to drop down to 3.55, but not convinced yet.

 

the 6 spd trucks had a 3.42:1 rear diff ... ... I thought about it ...


3.42's @ 4k ... omw ... thats a nice top speed ... about 160 MPH ish ...
...

 

and @ 3200 ... 128 Mph ... Nice !!!! and Disc brakes ... but the 1K for the diff .. Ouch !!

 

I am able to get this one cheap, helps knowing people that need favours. I am just unsure of the amount of work that will be required to get the rear discs to function properly and it is a gamble that I do not want to be tied up in until I am sure I have the time. I think I would be into at the least an aftermarket proportioning method and that is if the standard Booster and master would be sufficient.

 

I have seen a few do i t... they never needed more than just the diff and bleed them .. Done !!

 

Humm, now you have me more interested . It would be nice to have reliable brakes on the rear.

 

Thats my thought ... I would like to pay you to grab me one while your there ...
...

 

Just dawned on me ... your on the East coast ... LOL... nice lil drive there!!!!!
