250 vs 300
The short of it is this. We have a 73 New Holland 1112 swather with a 250, or so says the valve cover. It just kicked a rod. We are waist deep in haying and need an engine, there is a used 300 local for $250, but doesnt have manifolds. Will the 300 drop in and can we use our manifolds? I know they are the same bell pattern, but thats all i know. Also, is there a way to know for sure if its a 200/250 vs. 240/300? My grandfather and i were both thinking it was a 300. Number on the block he found is 6DZ. Im assuming he didnt see / couldnt find the decade code.

Also....no, the manifolds will not swap over. Is it a diesel or gas engine? There were several 4 cylinder diesel ford industrial engines used in different ag equipment. Do you have the ability to post photos? That'd be helpful. If not, shoot me an email.

Would make more sense to have a 300. Which site did you find this on? The two i looked at said they had 250 and 300 I-6, among the others you mention. Thanks for your help guys, ill try to decode the number he gave me now that im home, and see if i cant spot the difference in the valve covers.

So the only way it has a 250, is if it was put in there, if thats the case, a 240/300 can go back in. The original engine did the same thing here 20 years ago or so.

Sounds like the 300 should fit without too many issues. Whatever is in there, its cashed. Even if it were a 250, as FTF (FoMoCo engineer) said, the manifolds will not swap over. If its a 240, everything can be swapped in an afternoon. Worst case scenario, and its a 250, Have you been able to locate any parts for the 300 locally? Where are you located? Might be able to scrounge some parts from members here.

200/250 I-6's have 7 main bearings, the intake manifold is made as part of the cylinder head.
240/300 I-6's are completely different than the 200/250 I-6's. Intake & exhaust manifolds bolt to the cylinder head.
240 I-6: 1965/72 Galaxie/LTD; 1965/74 trucks & Econolines. 240 cancelled at the end of the 1974 model run.
300 I-6: 1965/96 trucks & Econolines; 1980/96 Bronco's.

I went back to try and find that page with the listings and what do I find instead?

That motor has the filter up front and the roundish intake, just like a 250. It is said to be a 250, although they say 4 cylinder despite the 6 plugs visible in the picks.
OP needs to look at the intake and post pics.

The engine pic in your link looks like ours from what i can remember, but cant be sure. Grandparents had a funeral yesterday so didnt get a chance to get out and look myself, or have them look.
