After throwing a rod....yes, throwing a rod, I had to get a new block. The Block that I destroyed was a 69. I proceeded to install a 80 225 truck block and found out it was a little taller than my 69 wich caused some problems. After the 80 was in I drove it and because of lack of experiance of engine swaps, I desroyed that one too. I didn't check the oil pump in the 80 wich ended up being a dud therefore I put about 500k miles on it in 30 seconds, ruining it. After that mess I was in the right place at the right time and scored a rebuilt 67 225 .040. My problem is that the tourqe converter does not fit into the butt of the crank wich doesnt make sense to me. The flexplate fits however the inner circle is a tad larger it should be. The 69 converter fit flush on the 80 engine but when I went to put it on the 67 , it was too big. Inside the butt I can see what kind of looks like a race but im not sure if thats what it is. Maybe I can take it out?. My question is - Does anyone know if different year 225's have different cranks, as in, a different size butt-hole for the tourqe converter? After the past three weeks of my free time going to engine swaps it's getting a bit frustrating. Anyone? -225 love

The diameter of the register was changed beginning in '68. What you need to do is either change the crank or get a converter built with the small hub on it. :shock:

The change in the crank 'register' is the result of a change in the size and spline count of the 904 AT's input shaft, that got larger in 1968.

If there is indeed a "spacer" or removable race in the hole of the 67 engine, you can remove it and hopefully solve your problem.

Taking your information at "face value"... a 67 and older engine will not bolt-up to a 68 and newer Automatic transmission without the special converter outlined above.
Or you need to change the crank or the transmission's input shaft to get the everything to fit.

How would changing the input shaft make it work? Even then the registar is too small. Is there a trick? Also, anyone in the sacramento area have a 67< converter and looking for a 69?

If you change the input shaft to an older one (67 or before) in the trans,
then the input shaft splines match the 67 torque converter. With the
custom trans, there is no longer a need for a custom converter.

The "race" you see in the Crank register may be a pilot bushing if the
motor was installed with a manual trans previously. If this might be the
situation have the pilot bushing pulled out and measure the crank register.
Compare the crank register and the torque converter nose measurements.

How about this... Would grinding down the circumference of the converter nose 1/8'' affect anything / or even jst grinding it down? Other than that my other option is to get a pre68 and have it chopped in half and welded to my 69. BTW I have a engine from a 67 manual and the tranny from a 69 904a

I have heard ... cutting down the nose of the later torque converters
causes them to fail - there is a bearing or bushing inside the nose
and when you cut it down there is not enough "meat" to leave it
structurally sound.

This is just what I have heard, I have no personal experience on
modifying a convertor.
