Engine is stuck

just shipped a 1960 F150 with 292 and standard trans from Wy to Texas. Biggest problem being the engine is siezed. Removed the flywheel cover, put trans in neutral and with a screw driver in the pressure plate the motor will turn very slightly and I hear a thin metal sound like something hitting a heat shield. Stater is not hung up , generator and water pump are free, what gives? Truck sat for no telling how long after previous owner passed away ,but was discribed as a running truck when parked (aren’t they all) . Was thinking of removing the oil pan to see what’s going on and to get some more torque To turn the motor . I have no pressure in clutch slave yet, could the clutch plate be stuck to the flywheel? New to the forum and appreciate your time to respond in advance

You should be putting some marvel mystery oil down the spark plug holes. Disconnect fuel lnlet line at the pump so It doesn't suck grunge up to the engine and into the carb if it turns over.

I’ve been soaking her for almost a week now , puzzling thing is how it will move slightly but feels like it’s hittin something , hoping th motor isn’t shelled out . Plan to do a rebuild but not right away .

I would take the valve covers off too and soak everything oil. Sometimes the cam or valve train can be seized up.

Good idea

I’ll try that too, curious why it would move slightly but not turn over by hand .

thanks Guys

If a piston is froze at top or bottom dead center, the crank can move a few degrees because the rod big end is moving sideways in that posion, for a few degrees. Could also be a stuck valve or some other things I can't think of right now. It's probably time to pull the heads and have a look.

If it's been sitting a while it will take a while, be patient. A week isn't very long. Mystery oil should work, is a good penetrant. Pulling the valve covers is a good plan, for inspection alone. Check for any bent pushrods, proper valve lash while in there. Solid lifters. (you probably know all this)

Last year I had a 390 that wouldn't turn over. It was sitting on the floor of a garage for 25yrs. It turns out the distributor was froze. Once I got it out everything else was fine.

HF bore scopes are cheap. Buy one and have a look in the holes.

Got the motor out

pulled the heads , pistons are stuck in the cylinders . Pulled the motor , still soaking to free the pistons . New question : looking for a cam that will give the motor some nice chop , but won’t require new springs , compression or gear ratio , any ideas on what duration I’m looking for ?

We have a member in the 47 and older section who frees up stuck flatheads by putting some old oil or diesel in every hole and lighting it on fire. Cam questions are best left to the cam experts. Every manufacture has a good hot line and they will guide you to the package you need. Comp even makes a line called thumper cams, for guys who want the lumpy sound.
