T86/R10: I6 versus V8

I just read this on Fordbarn:

I didn’t get a response over there (the pre-‘53 crowd kinda dominates over there), so I’ll ask here: Is there a difference between the T86/R10 run behind the 292 V8 and the T86/R10 run behind the 223 I6? Or was the only break between the 292 V8 and the 312 V8? The latter of which received the T85/R11.

The reason I asked is that I'm setting up my Falcon 200 to use a T86/R10 from behind a '57 Ranchero 223. I also have a V8 bellhousing in case I someday want to run a 250 or a mild 289/302. I'm wondering if the 6-cylinder T86 is up to the task if not abused, or if it would be better to seek out a V8 T86 for if/when that happens.

I would think a T85 would be overkill for those applications, however.

Thanks,

Dave

 

While I cannot tell you I know with absolute certainty, my belief is that the T86 trans is the same capacity for both the six and smaller V8's. There may be a difference in ratios between the two, and in theory that could affect it's torque capacity, but I seriously doubt that small difference would be worth worrying about.

I didn't start out with this post with the following comment in mind, but did just think of it. I have a '63 Ford Galaxie trans, 3 spd w/OD. It is, technically, a 'top loader' (tin cover on top, gears go in through that opening) but I don't think it is the same as the HD units usually referred to as "Top Loaders". It has the '49 thru '64 bolt pattern.

Same as mine. The 1963 Econoline bellhousing has the '49-'64 trans pattern on one side, and the '60-'65 Falcon engine pattern on the other. A factory-built adapter to run a big Ford trans behind a Falcon engine!

Thanks for the input on the T86.
