C6 strong enough for Cummins?

[TOYOTAJUNKIE]

I am looking to do a 12v swap into my 78 crew cab, I just had new drive lines done by jess and spent allot..

So I wanted to keep my c6 with married np205.

Is there any thoughts on this.

Can the tranny be reworked to have lower shift pts..

Thanks

I tried to search and nobody keeps the c6 for the swaps

WTF is with the cummins into fords all of a sudden? Granted its a great engine, but...

Can the c6 even be adapted to a cummins (and not cost you more than the new drivelines you got)? If not, that saves you the research on the strength of the c6

EDIT: Or is this the same person as 12vbandit?

Well the fact that a new rebuilt 351m will cost 4k to build and only put out 350hp and 450trq at 7 mpg

a 97 12v with 110k miles is $1800 at the yard and will get 20 mpg
$200 worth of springs and plate work I can get 350hp and 550 trq

And yes they make the adapters for cummins to c6

But I thought this was a ford forum and guys would know the Issues with the c6


thanks

I'd check fordcummins.com, even contact them as I'm sure they'd have some insight on the strenghts of a C6.
My gut opinion is Yes, enought strength if built for it.

I'd look for a C6 from behind a 6.9, from the factory they're set up with lower shift oints and more clutches than any other C6. The only thing that may be a PITB is setting up the VRV valve on the Cummins IP. The VRV regulates vacuum from the vacuum pump with throttle position so the vacuum modulator works the same as it would on a gas engine.
I'm sure that a C6 with a good torque converter would handle a Cummins no problem, but, the lack of lockup will suck.
