Looks to me like a custom made driveshaft would probably be cheaper, no?So for the driveshaft I have ideas, but can not find technical dimensions of the 66RFE vs the G56. I need to know the difference in length for my idea, so I was wondering if anyone can help out. I can not find or not sure how to find out.
I "think" (do not know) that it will be expensive to to have a drive shaft lengthened and balanced so instead of dishing out that cash. Lets put that money into something more useful...
So that big idea is an under-drive or AKA strongbox (check this out https://www.behemothdrivetrain.com/pages/strongbox-specifications ) to fit between the G56 and the BW 44-47.
Problem is to find splines that match the input and outputs. So far it's not looking good and by the price I'm not sure which way is more expensive. I also looked here to.. https://northwestfab.com/collections/ford-np205/products/blackbox-standard-1?variant=43246802075811 There are others but do not have the selection like these two do.
So if anybody has inputs please post your thoughts or experience
I think so, but still have questions about pinion angle, which may not be an issue depending on length difference.
If it needs to be longer, the pinion angle will only get better. Regardless, you can always play around with pinion angle.
Good to here from you @907powerwagonGlad to see this is still on-going! Sorry for such a long break but I was doing training there in Texas and it required all my time. Sadly, I had to abandon the swap and just get my auto rebuilt so I could get moving back to Alaska. It works great now but I would still have rather had this done, especially considering it was 10k just to get a factory rebuilt transmission. Oh well
Maybe this will still be an option in the future. I’ll be around if I can help anyone but it seems black gold is further along than I ever got! Can’t wait to see how it plays out!
A factory tranny cost 10 grad .. ouch my second last rebuild cost 4 grad and the last one cost 6 grad so I'm no further ahead.
Have no choice now, no turning back the G56 is in the truck according to my builder. He hasn't answered me back yet with what we have chatted about here on this forum.
That would be much appreciated the measurement of the driveshaft from White six four helps too. Which made me think that finding a drive shaft from a 3500 chassis cab might be an option but still means that the cross-member/transfer-case still need to reposition. The main thought behind an under-drive is to see if adding one would keep my cross-member and transfer case in it's place plus add a very low crawling gear ratio.
No, the G56 is a G56 but bell housing and input shafts are different, also the parts between the engine block and tranny are different to a Cummins too. I got the parts list from Ram chassis cabs were the G56 was offered behind a 6.4... but that 6.4 in the chassis cab is not a MDS engine so the cam and valve trains parts are different, also the tune is different too. The chassis cab 6.4 trucks only had a claimed 370 HP not the 410 in mine.
