Rebuilt engine but been sitting for years

So, I bought this motor a few years ago from a trusted source. As it turns out, it was originally built a several years before I bought it but never paid for. The builder hung on to it end then sold it to me. I knew the person it was built for so I had a good idea of what was in it. Do I need to do anything special to this motor, other than priming it, before turning it over for the first time? Friends have raised concerns that it's been sitting for so long (literally like 12 years on the stand!) but the builder told me this won't be a problem. Naturally I'm worried. Your thoughts?

If you can turn the crank by hand, I think your ok. Try that first with a breakover or equivalent on the crank nut.

Re: Rebuilt engine but been sitting for years

use some fogging mist in each cylinder to make sure the cylinder walls are lubed well.
I got some from NAPA

Re: Rebuilt engine but been sitting for years

I would hook up an external oil pressure gage and then prime to make sure it is making good pressure and well lubed. Definitely want to use a good cam breakin lube. How was the intake covered, carb, bag, rags, make sure there is nothing in there, like a bolt, washer, nut, or anything else. Harry is right make sure the cylinders are good and lubed and then rotate by hand, make sure nothing is catching the piston...
Then fire it up....My 396 was built in 81, then fired up 96. Had no problems...

When I bought the motor, the intake was off. I installed it but then noticed aluminum shavings in the runners so i took it off again and hot washed it. As it turns out, the intake had been port matched to the enlarged ports on the heads but never washed. Glad I noticed. I used some compressed air in the combustion chambers to blow out any shavings that may have got down there and looked around in each with a little snake light I have. The combustion chambers and intake are both good now I think. Do you think a tiny aluminum shaving would do damage to a cylinder wall if I missed one? I re-installed the intake with the proper gasket and masking taped all the holes. The motor has been wrapped in garbage bags for years in this manner.

Re: Rebuilt engine but been sitting for years

What was used for assembly lube? If it was White Lithium grease you need to tear it down and clean it out then reassemble (been there done that). W/L gets hard and crusty after a couple of years. Moly "B" also seperates so all of the oil oozes out of it (kinda like water from butter).

Re: Rebuilt engine but been sitting for years

Yes a piece of aluminum will eat a cylinder wall... If you even think there is a piece in there, take the heads off and check...
