my '72 i got has a 402 big block in it.
it sat for around 10 years or so and at some point a bit of rain must have got into the carb( not much we live in Arizona the dryest place ever) and there was about a 1 inch hole in the valve cover, that was not covered.how long i dont know, the truck was coverd by tarps here and there then they blew off etc through the years.IDK.
i pulled the valve cover and it was pretty nice, light dust but nothing more no rust or anything.

well, i checked oil and its beautiful actually almost new no water or gas in it.the engine is not frozen.

i was thinking marvel mystery oil down the cylinders and let it sit? new carb(rebuilt) on it and clean the surface rust from inside the intake.

any other options/opinions advice would be cool.i dont want to ruin the engine.its the factory motor id like to keep it in there

Make sure you pull the distibutor and reprime the oil pump and engine after sitting that long or you will eat alot of parts on start up from lack of lubrication.

This, plus crank the engine over a few times while priming to get that oil in every nook & cranny. Let us know how it works out.

id really think about cleaning out the gas tank as well, just went through that myself and could have saved myself alot of grief.
