904 Torque Converter in a 727?

[roadrunnerh]

This is the 10" TQ from my '75 Scamp 225 W/AC, 904.
The drive train had 53k on it, but doing 383 swap for fun.
What are the pros and cons of using this TQ over the 11" in my '68 727 440 Imperial Trans?
All of the writing was on the converter. Factory? Or rebuilt?

The biggest con is it will not work.

won't fit.

 

[pishta]

spline count and input shaft is different.

Thanks guys! That settles that!
Anybody interested in a gently used converter?

put a add in the "mechanical parts for sale" section.

That H/S is probably a 'high stall' from a land yacht.

spline count and input shaft is different.

Also the hub on a 727 converter is larger than the hub on a 904.

If the numbers are correct, the converter is a factory low stall (around 2000 stall) for a 1968-up non lockup 904 with either a 225 or 318 engine. The factory doesn't paint converters. Definitely a rebuild by somebody. Any converter builder worth their salt, knows that a 762 is a low stall 11" converter.
Could be what is known as a rattle can rebuilt, done in someones basement/garage.

Not worth the freight to ship it. Try a sale add here if you wish.

A couple of things. the 383 will have a steel crank, and the 440 has a cast/forged crank. See the attached pdf to see how to tell the difference between the two types. There is a difference in the balance of the two. Get your self the proper converter for your 383.

Never heard of an external balanced 440 in 68 or a cast crank 440 in 68.

Not sure. I know my 383 has a steel crank.
