Just towed my latest project home today, a 1951 Ford F2 pickup with a flathead V8, its an old farm truck that had been in their family since it was new. They parked it 20+ years ago and hadn't touched it since. We put a breaker bar on the crank pulley and tried to spin it with no luck, I didn't try to force it, because I figured it would be stuck. I bought a can of marvel mystery oil to pull the plugs and soak it down with and let it sit for a week. I'm just wondering what other people have tried, what works and what doesn't... I'd like to do as little damage to the motor as possible ( I know it'll need rebuilt more than likely). Couple of my buddies are really confident that we'll get this motor freed up and running again if it ran when they parked it... I wish I shared their confidence... on the positive side I've always wanted a truck like this with the flathead V8, she's rough but very straight, only dent is in the roof, and almost everything is complete except for the wooden bed floor that's rotten. It was kinda neat the grandfather( original owner) was there when we brought the roll back in and took our pictures next to his old truck before we towed her off.
