Studebaker 289 crank in y-block?

I picked up a Studebaker 224 V8 yesterday. The crank was out so I laid a 312 crank next to it. Weird, but they're pretty close. The Studebaker 224 crank's snout is rather shorter. I think some of the later cranks had longer snouts. The flywheel flange would hang out a bit more. When the 292 block comes back from the shop next Friday, I'll try laying the Studebaker crank in the block to see how far off it is.



The 289 crank has a 3 5/8" stroke.



If I have my information right, the Studebaker cranks are forged steel. Of course, all of this is academic. A steel 292 crank can be welded up to the max stroke that a y-block can hold. But it is curious.

PC; A Studebaker 224? Not positive, but I think their smallest OHV V-8 was from 1951 & was a 232 cu. inch, if that's what you are referring too...?

Paul, Until the day before yesterday, I knew nothing about Studebakers. I have a 53 pickup with no engine or transmission sitting under a carport, waiting for its turn. Then I saw an ad in the Craigslist for two 289 Studebaker engines, one running, the other for parts.



I picked up the parts engine and took it home and started educating myself. I found a website that lists crankshafts and it turns out that the parts engine is a 224 with a 2 13/16" stroke crank. Apparently, it was not a popular engine. I'm going to bet that the other engine is a 232.

Paul.  I’m aware of a 224 engine as well as the 232, 259, and the 289.  I had the 289 version in a ’51 Ford Tudor sedan early on and it was a strong runner.  The aforementioned Studebaker cranks had a 2.500” main size which is effectively the same as the 292Y while the Studebaker rod journals were 2.000”.

 

But here are some questions regarding feasibility of such a project.  Do you know what the bore centers are on the Studebaker block?  If the bore centers are quite a bit different between the Y and the Studebaker, then centering up the rods with the pistons within a Y block while using a Studebaker crankshaft gets difficult.  Also do you know if the Studebaker crank uses the center main journal for the thrust as that’s another consideration.  But if you can make all this work, then offset grinding the Studebaker rod journals to the Honda 1.889” sizes for a best case 3.73” stroke is also a possibility.  Just food for thought.

As I remember, Studebaker thrust is at the front of the crankshaft, and is even adjustable with shims.

John and Ted are right about the thrust bearing; it's on the front main bearing and it gets shimmed for clearance.



I just got two more projects to work on but maybe this weekend I'll pull the timing gear off the Stude crank and lay it in a 292 to see how it lines up.
