swap a 251 out for a 265?

[Greg51T&CWagon]

Looking at a running industrial 265 to swap out for my stuck 251. This is for a 1951 T&C wagon with fluid drive. Will this bolt up to the fluid drive etc? Potential problems with the swap? The engine I'm told is mid 50s.

thanks

Easy direct swap...except industrial manifolds, carb, dist and pulleys etc. Swap them off your old 251.

Thanks, I was hoping that was the case. So, I suppose the Spitfire head on my 251 will work as well?

Your 251 head will bolt right on.

just be aware of the extra water passage at the front ( bump on front of head water passage in block)  Spitfire engines in my experience did not have this feature

even though it appeared on other blocks in 1951.  Should you need to plug this passage in the block,  9/16 NF will thread the hole.

[Greg51T&CWagon]

All good. Well fingers crossed I can acquire this bad boy. It would certainly save me a lot of time and effort.

significantly better torque too.

If you swap the head onto a new block, use clay and check the valve to head clearance. Sometimes the DECK of the blocks have been cut and you can stick a head on that has been milled and the valves will hit. Better to be safe than sorry....

Thanks James, good advice. Unfortunately, it looks like this one is slipping through my fingers. The guy isn't responding to my calls.

like so many they learn after the fact they take an offer to find the "value" and by dropping communication they can back out of the deal and later sell it for more money... or could be just a matter of tied up with family and life....but I have seen the first scenario just way too many times....

[Greg51T&CWagon]

We'll see, but your first take is probably right in this case. the price was lower than scrap value. Let's hope he's just distracted at the moment.

As mentioned should be an easy swap.

The IND "cam profile", may or may not be an issue, sometimes the cam profile for industrial use, is engineered to provide lower RPM grunt, and a lower redline on total max RPM.

On the head, unless it was cut down a whole lot, most likely not gonna be an issue.

Heck you could use a 218 CDN Long Block head for a big compression increase, the 218 has the smallest CC of the heads on long block engines..

Dodgeb4ya and dpollo offer great insight into these engines. Both have several years of experience under their belts....

So looks like I found another possible 265. Fingers crossed. Picking it up first week of December. Not sure of displacement. It's out of a combine. 25" Chrysler engine. Could be a 251 which is fine. Taking it to George Asche for him to rebuild. Are most combines 265? or are 251 combine engines also common? Did they install other displacements in combines?

From the little bit that I have seen - it depends on the combine manufacturer. I've seen lots of Massey's with 251 engines installed, and that might because they also used that engine in their tractors. Oliver Combines - I think were all 265 (I have one engine, and have only seen 2 from this application, so.... ). I would definitely verify it either way, as anything is possible with the amount of time that has passed since they were new.

Thank you, I don't think he mentioned what type of combine it was? Is there any chance it could be smaller than a 251? I'm going to check the stroke when i go pick it up. The suspense is killin' me ?. a week and a half before I pick it up.
