c6 1500 ft lbs torque. whats it take?

What is required to make a c6 live at 1500 ft lbs of torque?

the trans in my race truck all ready has all the clutch baskets filled with as many frictions and steels as we can get in there. The frictions and bands are all kevlar and kolene steels. The planet set is the steel e40d version. I still have a stock input shaft which will be getting replaced with a billet.

I have been running this behind a few different stroker big block combos in a 4800lb 4x4 f100 for many years in sand drags and tough truck type events in addition to general play. I want to switch over to a 5.9 cummins diesel at about 900 hp and 1500 ft lb of torque. Rpm will never exceed 5500.

what will I have to address to make the trans reliable? Is it even possible?


thank you very much,

Nobody? This is a serious question.

Ive done a bunch of E4/4R's for the hardcore diesel guys, I guess if the c6 case is up to it and you can get the 2-3 tming down...... converter etc I dont see why not...... most of the hard parts are the same.

I used 6 frictions in the fwd, 4 in the int and 8 in the direct, Alto reds, Kolene treated steels w the black junk scotchbrited off.

if every thing else is up to he task as in the driveline suspension ect. I would think you'll have a traction problem before something in the trans will break. if you can get all that torque to hook.....?

The drive train should for the most part be up to par. I might need to swap the dana 70 rear for a 14 bolt though if I start twisting the pinion shaft off.

As far as getting it to hook in the dirt, it has to fight for traction with the 521 at 600 hp.

I forgot to mention the trans has a full manual vb. Would I still have potential issues with the 2-3 shift?

your trans will be fine ! they make the 727 live behind those things don't know why a c-6 wouldn't work ! good luck !

Thanks for the replies guys.  
So as I can gather the most likely component to fail would be the case itself?
This gives me hope for the build!

I still welcome any and all input on this build.   I will definitely be posting results.

I doubt the 14bolt is as strong as the newer Sterlings, and the Sterlings are a lot cheaper to buy and easy to find. 14 bolt axles are getting scarce around here and bring a premium price. I'm not sure exactly how much tq that Frank Merkl was putting down with that 700 + ci engine, but with the giggle gas, I'd bet plenty, and he wasn't scared of it.

I know the 10.25s are tough but untill I just looked it up, I never realized the pinion shaft was so massive in them. I work on them all the time just never mesuerd the pinion
