Is a marine 225 different??

There is a 225 near me that is out of a boat, is a marine engine different??

not by much- usually cam, brass freeze plugs ,bearings & some internals-yet no biggie.

unless its a reverse rotation engine they look the same. and thats all the difference is they rotate in the opposite direction of automotive. usually if its a reverse engine it came out of a boat with twins and an older version. 60's or 70's.
the only other drawback would be it will probably only rev to about 3500 rpm before it starts to lose power. boat engines were typicaly low rpm engines.

Thanks guys, I was on slantsix.org and read about the reverse rotation, but didn't think about the low RPM on a boat VS a car.

Seen as we are on the topic of different versions of engines being use for different applications. Combine engines...I have the industrial chrysler flat 6 in my combine from the late 50's and was wondering if anyone knows if motors used for farming machines could be used for street application. From what I understand these motors used in combines were built to handle higher RPMs and run in the heat all day long. I have the chance to purchase a 350 from a newer combine that has very little mileage on it. Are the blocks the same at the back or are they drilled different to hook up to a different transmission. Throwing this out there becus if you can't find engine parts in the street world you may find them in the farm world.
..And this chrysler 6 has all kinds of power.

Would the Heads from a Marine 318 work on the Regular LA 318?

where have you been hope every thing is well nice to see your back
