My 1965 Dodge A100 has a slant in it with a 727 transmission. I have a spare engine built up (Sept 25 1964) that I would like to install. Check the date on the engine in the truck and it is April 21 1976. How can I determine what the manufacture date is on the 727? (since there is that crankshaft counterbore thing that looks like it might come into play.) Also, the A100's 727 tranny was hung from the top, are they hard to find??

Look at where the engine and trans bolt together. See if there is an adapter plate between them (probably not). If there is no adapter plate, your trans is most likely the slant six case 727, and will not fit the 1964 crankshaft.

There are some numbers stamped on the transmission pan rail. Get those and I can see if they are in my transmission book (for the year).

I hope that helps. Thanks Matt

2508475 should be a 1964-'65 A100 727 transmission; 1336 indicates a build date of 24 March 1965. In other words: exactly what the vehicle is supposed to have. Small-nose torque converter/small crankshaft counterbore.

Thanks Dan. That is really good news!

I don't know for sure, but I'm under the impression, all 727 transmissions had the large nose converter.

Question for A100gary. Where is the starter located? above the oil pan rail, or below the oil pan rail?

My understanding is the 727 changed from small to large for '67, a year before the 904 did. But I'm not fer sher, either.

A little more research shows a change in the spline count (input shaft/converter)on the 727 trans. Small spline from 1962-1965. The big spline was introduced in 1965, but not all models. Both converters had the 1.810 pilot. I could find nothing about a smaller pilot with the 727 trans.

That must be what I was thinking of.
This site seems to support you on that.

The starter is located below the oil pan rail.

I'm not positive, as I don't have early van experience, but.
I think you have the small block style 727, with the factory adapter. A slant six 727 trans will have the starter above the pan rail. As far as I know the factory adapter will work with any slant six engine, but the crank adapter that is used with it, is for the small crank register, where your 1976 engine would have the big crank register. You might have to take things apart to see exactly what you have.
It is possible that someone installed a early crank in the later engine, or used a different crank adapter, at one time.
If you do have a crank adapter for the big crank pocket, you would need to get or have made a crank adapter for your early small pocket crank.

Hopefully someone with more experience will chime in, and correct me if I'm wrong

Definitely an A/LA-pattern 727 with adapter plate and crank-to-torque-converter spacer. The Slant-6 pattern 727 didn't exist til '68 or so.

I checked the engine on the stand-and it has the starter space above the oil pan. That being the case, will a bell housing be able to save the day???
