Thanks for the leads guys.
Yes, I have a lot of 68 materials including the resto pack that Chevy gives out as well as the service/overhaul manuals. My truck's engine bay is very complete and untouched right down to the smog pump. My engine looked exactly like one shown in a 68 truck brochure I have before I took it out.
The main question I have now is when is the most "correct" time to paint the block? When it's in pieces or after it's been assembled with covers and all like it appears to have been at the factory?
I don't plan on bringing it to any national shows but I would like it to look good in one of our regional show's stock class some day. I know they can get really nit picky with stock class vehicles. I don't really know what a judge will be looking for under the hood.
My truck's been retired from daily driving for a few years now.
Someone posted on the Stovebolt lounge a picture of a beautifully detailed (30's or 40's?) I6 before it had been installed in his truck a couple of months ago. Who was that? That was drop-dead georgous!
