Waking up a hibernating 327 small bock after a 22 year nap.


But as Vince asked, have you tried a rotation with the rockers removed and it's still jamming? Or have you just checked for open valves but not tried rotating it?

Sorry guys. Yes I have tried rotating it with the same result. About 330 deg rotation then a dead stop. Ditto in the opposite direction

if the cam is rotating the pushrods should be bouncing up and down.

Hmmm.... sounds like corrosion in one cylinder? Did one of the plugs look rusty?

It sounds like time to shove a camera into each cylinder. Either rusty as mentioned or something has made its way into one of the cylinders. Crazy as it sounds, a mouse can get in past an open valve on some engines. You never know...

 All the plugs looked good.  No oil in coolant or viceversa.

 Engine sat as it was after it was last run. Carb was removed and intake sealed off. Only rodent access would be through exhaust.  All the push rods move except a couple when the rotation stops. Lifter(s)stuck? No one agrees with my fuel pump theory? After 22 years should probably pull the motor and tear it down and refresh it? Dont want to ruin a small journal 327 screamer.

The fuel pump is simple enough, maybe pull it off and see if the rod slides freely? I wouldn't use a 22 year old pump anyway, it's likely going to fail shortly if it's not already bad.

I should have explained the mouse thing, yes I meant in the exhaust valve. I saw this not long ago on an engine that had been sitting in a shed. Mouse nest in a cylinder on an engine with heads and an intake on it.

 It is a small block after all.
