From the category of "It ran when I parked it".

I bought a 1970 GMC from a small isolated northern community with a great body. I has spent its life without seeing salt. The rocker panels are solid.

The previous owner claims that it was running when he parked. The clutch linkage is broken, so that makes belive his story.

Well it hasn't run in 5 - 8 years and the engine is seized.

Last fall I put some diesel fuel in each cylinder and now I plan to fill each cylinder with penetrating oil and letting that soak in.

Any other suggestions with tearing the engine apart?

My main question is where should I be attempting to gain leverage to turn this engine over? I haven't figured out a way to get a solid grab on the front of the crank to attempt tp turn the engine over. The truck has a 4 speed manual transmission, so I am trying to turn the engine over by twisting on the drive shaft with a pipe wrench. Any better suggestions? What gear should I be in? I figured my best mechanical advantage would be in reverse.

Oh yeah, the truck has a 350.
