Ok. Hence the countersunk holes. His just have multiple positions, right?

It allows you to move the axle 1" or 1.5". That's why there are 3 holes. You'll end up using 2 holes when you're done. I'm not too keen on the grade 5 bolts they want to use as the new center pin.

Don't cheap out and use the low grade hardware. Check out this problem we ran into at work. Link-a-ma-jig

Use grade 2, it will make things far more interesting when you put the foot to the floor!

Could be not enough manifold pressure. that was one of the problems the cat 3406 had. Swapping a holset turbo helped.

thosr things are too heavy. all class 8 truck engines can be fitted hith engine brakes and do not work on vacuum thy work on compression and the more manifold pressure the better the braking.We are getting around 30 PSI on a Cummins big cam 2 on the jake.

mknittle · 03-08-2013, 05:34 PM

Ryan, This is off topic but thought you might like to see this. it is still in the mock up stage on the grill shell. the engine needs to be moved back. and and and....

**Dieselwrencher** · 03-08-2013, 09:19 PM

And and and, sell it to me!

Nice progress on the ol girl!

Uh, yeah, you're totally right.

It'd get done if I quit improving on it every time I work on it.

Mattman2010 · 03-11-2013, 08:56 PM

I would use that word "improving" very loosely if I where you

**Dieselwrencher** · 03-11-2013, 08:59 PM

I got some time to work on it this weekend. I got the zero rates installed, and IDK if I'm exactly am happy with it. Before I started the wheel base was 132". After it's 133.5". So it definitely moved. I just don't think it's enough in the front yet. But I only moved it 1/2". I still have the 1 1/2" hole to try. I also stripped the other hole in my diff housing on the RH leaf spring retaining plate. So I'll have to heli-coil them. I had the inserts but no tap. I didn't realize the taps for a 1/2" heli-coil was an odd size. Go figure. I got the kit today though, so I'm good there. Any how, here's some progress pics.

I cleaned the bed out, removed the rear bumper, and slid the bed back. The bed was way too close to the cab for my taste.

Next I removed the bed so I can start on the GN hitch, frame boxing, and fuel tank swap. (Thanks for the idea Matty)

Almost had a casualty.............

No bed.

Tail pipe won't work when my hitch is finished. I'm planning on running straight pipe now.

Starting on the GN hitch. I'll have a B&W inbetween the 4x4 and 2x4 cross members.

Shoot, just this weekend and this morning, I bet I spent 10hrs working on this thing.

jbclassix · 03-11-2013, 10:09 PM

Exhaust pipe or Ia metro subway!

I agree, I think the axle needs to move forward still.

brothers69c-10 · 03-11-2013, 10:10 PM

Looking good buddy. Hope to see this one at goodguys this year.

ryanroo · 03-11-2013, 10:25 PM

Ryanroo was the one with the idea. I stole the idea from him for my gooseneck hitch. Hell if you read his thread he said he wished he would have spaced his so the b&w would set right on top
