Question on 5.7L Chevy V8 compression

[nestorpr]

Thanks guys, I knew I would get some good advice here. I'm going to reseal the drive anyway so I'll rebuild the pump then (I already replaced the impeller on the engine) and will check the manifolds, that may have been the cause of the overheat since the previous owner did tell me that they needed replacing. I think you may be right, after such a long layup the rings or valves on #5 may be stuck, I'll run her and then do a thorough compression and leak check. Heck, I may be up and running by March, Thanks!
