Block ID?

I've searched all over the block and the internet and still don't have any idea what is in my car. I need to know so I can get the right spark plugs and stuff to get the thing running!

Block has the following markings under the intake manifold:
front: 330 4
rear: 2660
rear: AAWJ

Do any slant 6's come with long threaded plugs and a tapered seat? I stuck my little LED flashlight into the plug hole and the threads seem like they go on for a while.

That 273 transplant is looking better and better... :read2:

Unfortunately my camera lens is stuck half way out and the camera is now shot. Can't a guy have SOMETHING work out in 2011? So far, not so good. :pale:
