Quick 904/727 Question
« on: March 16, 2006 - 08:13:58 AM »
Were the 727's standard on cudas? Im assuming it was standard on 340's and big blocks. Was it an option on the 318's or were they even available to them?
Were the bellhousings the only diffrence from the big block to small block trans?
What other mopar has the same dimensions, tailshaft wise?

Not to hijack the thread or anything, but along those lines, what small block combos can a 904 sit behind?  How much HP can they handle compare to a 727-A?

727/318 are often found in trucks & were avaia;lble in cars also
E body shares the long shaft version with 2 wd drive trucks , vans & A , B body & C body cars although not all tailshafts have provison for the floor shifter linkage support bracket mount
 the 904 can be bolted behind any small block & are often used for racing purposes , proerly built with good parts of course

OK, I have a 73 RV with a 440 in it and an auto. Are you saying that the trans and engine combo will work in the ebody?

If it has the long tail shaft it will. My cousin has the same setup out of an R.V. but it has a short tailshaft.
One of the other differences include: the 440-6 pak and hemi 727's deleted the spring in the accumulator. I can't remember why, but, when I bought the TCI tranny for my 440, I took it apart and removed the spring and installed a 3/8 inch diameter aluminum rod to hold the accumulator piston in the full down position. I think it fools the tranny into thinking it has more oil available to it or something along that line. Boy , its been a long time ! ! !  :undercar:

Chryco, what exactly does "properly built with good parts of course" mean? I'm asking 'cause I'd like help. I am replacing my 318 with a balanced 340 and want to keep my 904 because many guys say it frees more horsepower than a 727. I was going to buy a heavy duty rebuild kit for the 904, along with a new valve body, torque converter, kickdown lever, deeper tranny pan and I think that's it. And I'd have a proffessional transmission shop do the work. Would that be enough to handle my new power?

using top quality bands & clutches is part of it but often there are drums with with room for extra clutches & & extra surface area can make a big difference , also the planetaries can have 4  pinions as opposed to 3 pinion which adds strength so a lot of the hard parts can be replaced to improve strenght

I would go with the 727 and be done with it.
It is a very easy swap.
The 727 is alot stronger.
