    I just dug my 63 Wildcat out of storage where it sat for 16 years. She ran strong when parked but is seized up solid now. I keep pumping penitrating oil in the cylinders, and running the oil pump with a drill but she still won`t budge. ( And yes... I already stripped the flywheel and/or starter gear on the first attempt of starting it. ) LOL ! i`ll never do that again ! $$
    Any suggestions ?

    Probably stripped the starter gear.

    Try moving the motor with a breaker bar at the crankshaft bolt.

    16 years is a long time...maybe too long?

    yep, thats what i have been using, i`m going to see if i can locate a strap wrench with a 3-4' handle to grab the outside of the pulley. Hopefully she`ll move ?

    Got a floor jack handle (big one) or a large metal pipe?

    Stick it on the end of the breaker bar and sit on it.

    If it doesn't move then, it's not going to move.

    Take the rockers off. If there are stuck valves or siezed rockers the engine will not turn. Also you will get more leverage using a large screwdriver on the flywheel teeth.

    Hi, Dave
    This is what i watched my dad do on a seized eng.
    Both heads off,bolt a 1/2x2 inch strap of steel across top of a piston that is half way down. You need a 1/2 inch treaded hole over center of the piston. Sight correct location of hole by fastening the strap on the head first. Take an 8" pc. of 1/2" threaded rod and weld a nut on the end. Use the threaded rod as a "jack". Be sure to put a small pc. of Alum. or steel plate on top of the piston to protect it. Also, have someone turn the crank at the same time. The only thing you won't know is if your helper is turning the correct direction. A little trial & error involved. I was the turn kid & it worked.
    Good luck, Ron
    :cool:
