Re: [AMC-List] 360 Rebuild

[Matt Haas <mhaas@xxxxxxx>]

Todd,

I don't think you'll be able to check compression turning the engine by 
hand. You really need to use the starter motor to turn it over.

On the 360, if the two low cylinders are next to each other, it could be 
a blown head gasket but 90 PSI sounds low to me. There are plenty of 
other problems that you could have but the only way to know for sure is 
to tear the engine down. Since the problem happened all of a sudden, it 
will probably be easy to spot the problem.
