I have a rebuilt 350 that has been setting for many years and I am ready to install in my project truck. The question I have is how should I check the 350 out to make sure I have a running 350?

Thank you for your help.

Depends on how it was layed up and taken care of, climate controlled? Sealed openings, etc? I'd be concerned with lack of cam break-in lubrication, rusted cylinder walls, valve springs that have taken a set if left compressed. Does it rotate freely? I wouldn't try that without putting some oil in each cylinder, and not rotate it by the crank bolt. Was the carb left out in the elements? Is the distributor clean and rust free?

Definitely needs a good priming of oil for sure. I would spray some lube into the spark plug holes and some fresh oil and filter. Next use a priming tool and spin your drill while turning the engine by hand. If all feels smooth, i would put in the distributor wires n plugs and crank her up on the stand or in the truck. Good luck. Oh and dont forget to add some zddp additive to your oil to save yourself from flattening a cam lobe!

Are you wanting to know if its frozen up, ring stuck from setting so lond, I start by putting it on and engine stand with oil in it, prime with a distur. tool to build oil pressure, after it starts in most of the rockers turn the engine until oil come from all of them, then do a compression test on.
