engine assembly

[SShep71]

The amount of time the motor sits for wont be a serious problem. As long as you use the proper pre-assy lube on the cam lobes and assemble everything correctly. With a light coating of oil on the internals and sealing the engine up moisture shouldn't be a problem either. The most important things are using the proper break in oil with the proper additives and also pressurize the oiling system prior to start up.
