Makes me wonder if the reason it was pulled is it was a mis-match of parts and that lead to problems that were easier solved by pulling and selling (or giving away) the engine in question?

What’s really puzzling are the pistons. I inspected the pistons and valves with a borescope. The pistons are flat top. I thought the tilt valve had to have stepped pistons?


Yes, the compression will be low with flat top pistons and a tilt-valve head.

Make a good "blower" motor, likely get 2 bar without detonation!

If you are speaking of "blowers", the Ford Thunderbird SC had an Eaton M90 supercharger on a V6 engine. These "blowers" are easy to find, adapt and buy at auto wreckers. I bought two M90 for $100. This included the intercoolers.

If you are referring to a turbocharger system, there are aftermarket kits for IHC tractors. I think one of this form's member had a similar system on his IHC R120.

Years ago, on this site, there was a guy who had an SD with BD tilt-valve pistons and a straight valve head. His complaint was that his engine was hard to crank over. Finally figured that, with that combination, he was running about 13:1 compression.

I would imagine that, with the opposite combination, you MIGHT have about 5:1, maybe 6:1, compression. That will make an engine that, as Pappy used to say, "wouldn't pull a sick [prostitute] out of bed."

But it'd be a PERFECT candidate for the Keystone turbo!

Well that would stink If the tilt valve head was that low of compression.
The block is a SD240 SN 59713. The head is a tilt valve casting no 254544C1.
I was told they pulled the motor to install a Chevy for more power. The water pump bolts were busted so I was hoping it was pulled due to a bad pump.

Correct me if I’m wrong but the SD240 and 220 have the same PN head in the parts book. I could have the head for my SD220 overhauled. It is straight valve. I also have all new valves, guides, and head gasket. Seems like I should swap heads.

What do the top of the pistons look like? If they are "step" pistons, I do not think they would work with the straight valve head. I could be wrong and someone with a better memory will speak up.

Lloyd, I think he already mentioned they're flat tops.

Thanks, missed that, so the head he wants to use would work just fine.

Check the rear main seal while you have it out. Ya never know.
