I have a 413 with the longram manifolds that I will be installing in a 31 Plympout coupe and want to use the 833 4 speed trans. What will I need to do to make this happen

Thanks,
Bill

 

You'll need a bell housing to fit the 833 and 413. The trans will bolt to the bell housing. Get all the correct Z bar linkage and whatnot. Custom drive line. Probably have to hack the floor up to get a shifter to work.
Ect.

 

dont for get a input shaft bushing in the end if the crank. it is a remote posabity a 413 may not have the hole for a bushing.

 

Yes check the pilot bearing hole out CAREFULLY. Chrysler was not only bad at leaving these undersized for auto cars, but not DEEP enough. A common fix was to chop about 3/8" off the transmission shaft. be sure to measure that depth carefully and make sure you have clearance.

I don't remember for sure, but it seems to me early engines had a different crank flange, and some heavy truck/ industrial 413's certainly do.

 

i would hate to chop the input shaft one mistake and your finished, and what if later you still got the trany and now a new motor with the proper pilot hole in the crank?

 

This, "back in the day" used to be a fairly common fix. It does not hurt the transmission. If you have ever seen the shaft on an A-833, it has a very large and long chamfer. Basically, you cut this off, so you are not losing much if any of the actual shaft length. These have a very long pilot, and plenty of room.

"One mistake?" I'm not suggesting you use an axe, cutting torch, or stoneage tools to perform this operation. On the other hand, careful thought with a hacksaw will result in an acceptable cut

Your alternative is to find another crank, or pull the crank which is in the engine and have it machined.

 

Going into a 30's model anything and fab is GOING to come into play, z-bar linkage wont be 'out there', in this situation Hydro is the way to go, as nothing from 'stock' will not work without modifications....

 

This rings a bell , I think they may have had a different crank flange depth . I never trim the front off the input shaft you can deepen the hole easily & use the Dakota roller pilot brg in the torque converter recess instead .
I agree with using a hyd clutch , Tilton & McLeod both have hyd release brgs available , I like the McLeod design better having used both .
