While looking for a 270 for my truck, I ended up with two of them.
The first is out of a '58 two ton with a sealed valve cover and what looks like a rudimenery PCV system. It also has a sticker of some sort on the side that says its a remanufactured engine.
The second is from a '59 1/2 ton with a vented valve cover.
I noticed other subtle differences between the two, but the thing that puzzles me the most is the engine from the '58 2 ton does not seem to have vacuum advance. The distributer is fixed in place and has no vacuum line to it.
Is this normal on a two ton truck?
The engine from the '59 1/2 ton has vacuum advance.
