Went to look at a 57 Eagle yesterday with a Cummins engine. Couldn't get close enough to get any id from the engine and was hoping that someone familiar with Cummins might be able to ID this engine from my poor pictures.
Thanks

No clus on the engine but how about a pic of the bus? ;D
-
Looks like a old NH 220 to me right time line and some Eagles came with that engine if is it a high roof Eagle probably factory
good luck

Tim, Do you have a VIN#? Would be neat to find out where it started it's life. Clifford probably has the answer. 8)

Thanks guys
Paul...VIN is 27756
Pics aren't very good due to pouring rain. It has been sitting for about 4 years.
The fellow who owned it has passed away and he lived in it for quite a few years.
Thanks again....Tim

Oops...managed to attach pic of MC6 I looked at day before.

1957 Golden Eagle 27756 went to Cont Dixie Lines. Are you going to save it?

That is a Cummins NH engine. If no turbocharger-will be 220hp and about 650lb/ft torque (on par power wise with a 6-71N Detroit). If it has a turbocharger will be a 262hp with about 750lb/ft torque. Good engines-just lacking in power compared to new engines. You could pull that one out and replace it with a smaller L10/M11/ISM engine that will get up to 500hp and 1550lb/ft torque. Good Luck, TomC

Faulty memory. Didn't the old older (but still fine!) Cummins 743 inch 220 hp have a noticable gap between the heads? Like enough to squeeze a little finger between? The heads on your mystery motor seem very close together.
Also, again if memory serves, didn't the 220 series have six (6) exhaust headers on the exhaust maniford? Dunno. You pictures show only three(3). We need better pictures. What did Cummins have before the 743? HB of CJ (old coot)

as has been said it is a NH 220 see the fuel lines going thru the heads. You could turbo it like boogiethecat did to his. he used a wastegated turbo set at I belive 11 lbs of boost. If you need engine parts let me know I know a guy that has a lot of small bore parts in his sea train.

There is a gap between the heads-just can't see it at that angle. The picture is taken on the intake side. But yes this engine does have 6 individual exhaust ports. Cummins also made a 150hp 4 cylinder version of this engine which was actually the first engine to come out before the 6 cylinder NH engine. Good Luck, TomC

In around the same time frame Cummins also had the J series engine smaller in size with 401 CI but they could produce more hp than the NH series we called the JT Cummins just trash for short lol I am not going to tell you guys what we called the JS Cummins.
The T was for turbo the S was for super charger (blower) they did the same with N series also
good luck

I remember in the 60's and 70's Cummins having the JS series that were used alot in trash trucks and concrete mixers. I can remember because the supercharger they used was a two lobe roots type that had a definite whine-almost a whistle-to it. Much like the 53 series blowers as compared to the 3 lobe superchargers used in the 71 and 92 series. Good Luck, TomC
