Bob,
Just make sure to check the block and the heads separate of eachother.
It's very common for an iron block to be mated with aluminum heads.

I'm looking at a nice little fishing boat/cruiser with a Detroit 353,
only about 1000 hours on it, runs great. I know this is one of the
more reliable diesels ever made, but I have heard some not-so-good
things about the ones that came with aluminum blocks. The boat was
built in 1987, so the engine is at least that old. The owner doesn't
know much about it.

Is there a way to tell which version it is?

Thanks,

Bob

Uh, duh --- I plead brain fart! Sometime the obvious solution just
ain't so obvious. Of course...


Anybody know what the problems with the AL block versions might be?
Haven't heard any specifics, just "don't get one with an aluminum
block".
