Who has a big block truck?

[Tx Firefighter]

I'm wading through this big block conversion. I need pictures of STOCK big block setups in these trucks. I DO NOT need pictures of modified engines. I want to see what it should look like in all it's GM glory. Need pics to see what color stuff should be, what the vacuum hoses looked like, air cleaner, water neck, plug wire routing, everything.

I'd really like to see some pictures from literature depicting these trucks when they were new and unmodified, or at least a decent original untouched truck.

Thanks,
Kevin
