Don't use WD-40. Get Marvelous Mystery Oil to lube the cylinders before trying to start it up. Let it soak for a few days then take a socket wrench and put it on the balancer bolt and see if you can turn the crank before proceeding. After you determine the engine is not seized up it's just a matter of getting fuel and spark.
Good luck - you adventure is just starting.

They make fogging oil, engine builders use it all the time.

Okay so today, I put the 1978 Z28 5 spoke chevy rally rims and they fit...just if anyone was interested...their on temporarily, while i do the restoration :-)
Also, when I had to jack the car to swap tires i did a better inspection all round under the car because i didnt really do that at time of purchase, circumstances were hard...I noticed the frame rails (rocker channels) that run along under the doors are pretty rusted out in spots and probably wont pass certification. Funny enough every other area of the frame looks good, just the rocker channels under the doors on both sides. Looks like the car had been undercoated with black tar maybe from factory.
My question is can the rocker channels be fixed without taking the whole car and body apart? Can a shop weld in two new rocker channels? to pass safety? thats all this car needs. I think. Any help?...see attachment pic on where its rusted out...thx - jamie

Rusted through or just surface rust? If it's rusted through then the body will have to come off as you can only see a portion of the frame rail and if it's rusted though where you can see the parts you can't will be bad too. If those are rusted through I'd hate to see what the birdcage looks like.

I prefer using other types of oil for that purpose but it wouldn’t hurt. Basically just getting oil into the bore and onto the top ring lands to help free everything up. I personally would use ATF but WD40 shouldn’t hurt. If you put oil into the combustion chamber you want to roll the engine over with the plugs out at first so you dont possibly hydrolock the motor.

post pics of the rust. If it was sitting in a barn with a dirt floor the frame could have rusted from the bottom up and the birdcage could have survived

The channels have surface rust, also a hole here and there, but mainly rust on the rocker channel frame. Maybe like some said, because that part of the frame is closer to the ground, the moisture in the soil may have increased the deterioration of that area. where it was sitting for years was soil and not concrete...Also, i think if i remove the chrome rocker panels I should see more of the frame...the birdcage is under the body? I'll have to see if I can see it, maybe its rusted where it meets the frame...I'll take some pictures this week and post them...
thanks

Unfortunately the 10 Rules for buying a Corvette lost the first post, but post 107 copies the first post in its entirety, including pictures of a bare birdcage.

Your best option might just be to enjoy the car (if the chassis is safe to drive), until you are ready for a frame-off restoration.
Good luck!
