I may try to run it like it is for now after I adapt a trans etc

If I remember correctly they had different governors and delivery valves but not much else different.
I'm hearing a different govorner spring, fuel pin and I need to find out if it has air fuel control on the injector pump which is a diaphragm lookin device that I can rob off another pump or get a new vee pump.
Dynamic timing control is also something I may need. The ve pump has dynamic timing control which may be better for on road use up to 500 HP.

Against My better judgment I'm leaning toward keeping the Allison since it's already adapted to the tcase. Biggest issue is I need to find a stand alone tcm and harness for a 5spd 1000.
Destroked.com has one for a 6spd but I'm not sure if it will work. From what I understand the 5 and 6 use the same case and the difference is in the planetaries. I reached out to destroked so hope they'll get back to me.

There is no mechanical difference in the gear train of a 5 speed Allison to a 6-speed. They are commanding the clutches in a different sequence to get another gear in the middle. No extra planetary gear set.
The changes are all in the valve body and the case to have the revised circuits to allow the different application of clutches to get the extra gear.
To my knowledge without a lot of work to the valve body and case it isn’t really easy to make a 6-speed out of a 5-speed version.
If you do plan to keep the ally then don’t add the complexity of trying to get the extra gear.

Good to know. I was going off training I took at Allison in Indy during my time at Workhorse. That was about 18 years ago.Duramax Tuner Allison Six Speed Conversion

I’m not sure if it was mine if I would go through the effort to make the change. As the article is pretty clear in the needed changes, getting it wrong is highly possible if you aren’t well versed in Allison transmissions.
Given all that has gone on in this build I’d take a keep as simple as possible approach. Stand alone controller and harness is the best way to go.
I have heard that the Allison has the torque capability, but in stock form it isn't set up for the rpm range that the Cummins makes torque. The inline 6 makes torque at a lower rpm range. I don't know if just programming can take care of it, or if pump modifications with pressure and flow adjustments will be needed to hold more firmly at lower rpm.
Yea the last thing I need is extra complexity lol. I have hears of a 6 spd conversion I'm not to interested I just don't want to smoke the trans
Kinda my worry. I'll definitely get a new converter so it doesn't ruin the trans when the stocker melts but I know their weak point is the 3rd gear clutches don't get cooling bit there's a pto cover plate with I diverter that supposedly remedies that.
So do we thing the stand alone for a 6spd will work on the 5 speed?
Wow.. glad you are moving along with it. Was nice meeting you in person and seeing truck before the incident... Cant wait to see how the cummings does!
You're recovering from this well, much faster than I have. Mine burnt to a crisp a year and a half ago, and I still haven't gotten back into wrenching. The whole experience left a bad taste in my mouth, and I needed some time off. I'm almost ready, though. Starting to get that itch again.
so my sons nissan 350z 5.3L swap caught on fire...so I went and bought fire extinguishers... small ones and mounted in garage on each side of garage doors... his car is salvageable and a shop is redoing it...
3w later, working on my 8.1L swap..she was runnin great till warmed up so someone said put stock fuel reg in cuz sounds like autozone one might b my issue.... truck was ice cold.. turned key, started cranking and...whooosh... up in flames... i ran and got an extinguisher and used the entire thing... went out..few seconds and whoosh back up.. used 2nd... my fire, i hope didnt hurt much...
took weeks for me to look at it. It is in my driveway and I am starting.
My fire was a loose fuel return line adapter to 6an... 3w later my son tells me his friend.. her car burnt to a crisp.. 5.3L swap some kinda car... so weird all these fires.
Doubtful. I’d ask directly to the company the compatibility between versions before buying.
So I got it home! My 3450 kubota did not like taking it off the truck! That's why the pic are with it on the ground I wouldn't get off the tractor until it was landed.
So I hooked a battery to get the hours and it has a little over 5k. Not bad got an engine that was run at 1800rpm its entire life. So much so that the exhaust is pretty "wet stacked".
I'll probably remove this injection pump and swap with a truck ve so I don't have to change the entire front cover etc for a p7100 pump. The turbo is too small and from what I hear this exhaust manifold with crack the head due to heat cycling. The oil sump is to the rear but I need to find out if it still needs to be swapped.
Now as for drivetrain, I really think going with the Allison makes the most sense but the catch is it needs a stand alone tcm and I haven't found one yet...

Not to derail but to add info.
There is a slightly better than snowballs chance in hell I could end up with this. Good, bad, ugly?

That looks identical to one out of a genset I used to maintain in the Florida keys'08 or so but the same engine I have. I'm still learning about the pumps so I dunno
Don't ever pass on a Cummins for a good deal.
