Foreign Engines in Lynnwood. They regularly receive containers from China. Almost all of it is stock stuff though; if you are looking for a modified long block or short block, you'd best get it here. Northwest Nissans occaisionally has someone post something like that.

For shops, I would only suggest Garage Autohero in Lynnwood, though Drift Office and Up Garage are nearer to you.
