Lets see if I can explain better. I used the same sae4 housing adapter as everyone else (standard thickness) with the shorter aluminum housing.
When I originally adapters from PC I did not know there were different housing depths. And got the cone shaped 10" flywheel adapter that was to tall.
I called PC (talked to Jim) and he suggested the added spacer idea to make it work. I did not have room in my sonoma to do this.
The flywheel spacer I used is a shorter version that is shaped with a center cylinderical shape instead of a cone. When I bought it Jim said they had only made 3 or 4 like it and had sold them to cummins in colorado. I will see if I can find the part # at home in all of my paperwork. So it was something they had made in the past just not many of them.
Definetly helped with weight and length it sounds like compared to other setups.

Do you have pics of the cylindrical flywheel adapter?

Hey,
thanks for everybodys reply and input. It looks as if everyone had the same engine, but different flywheel housing and flywheels. I think I will stay with my original plan, as TDIwyse. I like the idea of flexability in the future. Also, I'll keep my aluminum short flywheel housing if I decide I need/want to reduce weight. My concern with all aluminum would be the durability. Hopefully, no one experiences any problems. Macet or Sonoma3.3, did you consider tack welding the spacer to the tranny housing? I ask, because it may give additional stregnth. I would be looking for stress fractures on the housing. I am not an expert in welding or mechanics. The aluminum bellhousings are used on stationary generators and don't have the same stresses of a moving vehicle (ie, speed bumps, pot holes, etc.) and the torque of the driveline. Just my 2 cents.
Does anyone know why PC uses a cone; instead of a cylinder or a solid cylinder as flywheel adapter? My initial guess would be that the cone shape is stronger than a hollow cylinder, or maybe the shape reduces weight, or maybe can handle the driveline torque. Just curious.
Thanks,
Chris

Before you go too far with the 3.9 method let me tell/show you what I had to do.
1. Had to drill the dowel pin hole to .5 to accept the larger pins on the adapter.
2. Drilled and tap two 3/8 bolt holes in the adapter. Probably didn’t need but I would rather do little things like that while the engine is out.
3. Had to Weld bushings on to the housing to Bring the heads of the two bottom bolts out so I could get a socket on them.

Would a box end wrench work without the bushings? Or could the bolt holes be spot faced to facilitate a socket?

What are your EGT's and boost? You went a little more timing advance than what I'm at. I wonder if that and the warmer weather is causing it? Is it more noticeable at your peak torque rpms? According to this the timing may be part of the issue.
http://dodgeram.org/tech/dsl/FAQ/timing.htm
Mine puffs a little black on startup and during shifts if I romp on the fuel. The smoke clears up as the boost increases. Our differences might be a combination of the intercooler, biodiesel and slightly less timing advance?

I do have guages and have seen an increase in exhaust temp. I guessed it was temperature related but just suprised at how drastic of a difference I have seen. I can see my tail pipe out the passenger mirror so it is easy to tell how bad it is smoking.
Looks like i need to look into that intercooler I keep thinking about.

952Z84,
Thanks for the reply. Thanks for pointing out that the 6bt and 4bt both use aluminum flywheel housing. I figured the torques would play into the shape of the cone.
Speaking of the 4bt, when I picked up the Wonder Bread stepvan on Friday, I spoke with one of the mechanics. He said the best way to achieve more hp is to inject propane. All Interstate Bakeries maintenance vehicles have a BBQ propane tank behind the drivers seat. He stated you could dump more fuel into the motor, but it will likely cause black smoke.
Here's a website on how to make your own propane injection system.

I don't know if the acetelyne gas regulators work on the newer propane tanks.

The two positions I welded bushings on are the two below the slave cylinder 7:00 & 4:00. There wasn't enough room for the head of the bolt. With the v6 the bolts are installed from the front of the tranny. I’m not sure what spot facing is.

Macet,
I now understand drilling and tapping the two holes in the ring adapter at 7:00 & 12:00.
I apologize for my lack of understanding, but I still don't quite understand the need for the bushings at the 4:00 & 7:00 positions. You stated "With the V6 the bolts are installed from the front of the tranny". If I understand this correctly, these bolts are installed from the engine side of the bellhousing? Were these bolt holes threaded? I'm thinking that if the bolts used nuts, the bellhousing would be cast/machined with a surface for the nut to seat against. In this case, no bushing or spot facing would be necessary for the bolt head. Correct? Or am I misunderstanding you?
Mike

Pretty sure now my smoking issue is temperature related. 35 deg in chicago this morning and truck only smokes on heavy accel and then clears up. Once it warms up a little bit again I will have to play with my timing and fuel settings.
Also I got my double crank shaft pulley last night. I ordered it through my neighbor ( heavy truck mechanic and builds 5.9 cummins for pulling trucks)
$123

Were you going to use this to drive the AC compressor? Let us know how that works.
You've probably got a bit of time before you need the AC . . . it was just under 30 F this morning
here in Iowa.
