2nd engine down
77 Pontiac lemans with original a 350 oldsmobile. I yanked that out and found a 403 at my local engine mechanic. He rebuilt it but it took some time for me to stab the engine in. Plus $$$ obviously. In the time it took to try get parts and everything. It locked itself. So it's stuck. Will keep you posted!!

Maye some kind of obstruction?
A well oiled fresh build would take some serious neglect to be unable to be turned. Try the flywheel end.

Even if the engine is stuck due to rust, it likely can be saturated with some penetrant for a week or so, then broken free by applying pressure on the flywheel side, as already suggested.
You could also get a inexpensive bore scope to look into each cylinder to see what you're dealing with too. Unless the engine was filled with water, I doubt all is lost. I've seen some engines brought back that were filled with water, that run no different than one that hasn't been frozen up ever.

A little bit of update the machanic that rebuilt the engine suggested the same thing. Or also that it may be the torque converter, not stab in correctly, so I have to pull the engine back out and see if I have the third click. Here's hoping!

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
