What climate has it been in? Not a good situation for an engine to sit for years. Condensation will cause rust spots on cylinder walls. Seals dry out because the
oil/assembly lube wicks off after time.
If it wasn't dyno'd, there may be a greater cause for concern. You're now dealing with rings that haven't been seated, but are now going to ride across dry and possibly rusty cylinder sleeves.
I would squirt some
oil or WD in each cylinder, fill the engine with
oil, then prime the poop out of it with a priming tool. Roll the engine over by hand turn by turn while priming.
Go over all the external fasteners.
Keep in mind that since it's in an "un-broken-in" state, I would do this, fire it, then drive it as soon as possible and for as long as possible.
If you're not sure on how to get the distributor back in the right spot so it will fire, we can help you with that.
