Hi from Arkansas

[Bolt]

Me and my '79 High Sierra want to introduce ourselves. It is a heavy half with the original 454. Truck has been sitting for 20 years so I have my work cut out for me. Motor is seized which I have been unable to break loose. Any help would be greatly appreciated!

Yep, been setting outside for a couple decades. The motor is stuck. I have tried diesel and Marvel Mystery Oil.So far no luck. I think I may try and pull the engine out and see if I can get it to move.

Pull your plugs, and fill the cylinders with PB Blaster, and give it about a week to sit.
