This picture gives you an idea of how to run the plug wires. If you need a paint code for the engine I do have it on this site somewhere. I had a small patch of paint left on my oil pan when I rebuilt the engine and I did a color match. This is m rebuild thread.
https://67-72chevytrucks.com/vboard/...=795604&page=3 I was going for stock appearance as much as I could. One can see I do have a power brake booster and dual master. I also got rid of the road draft tube and installed a PCV valve along with a 4 barrel carb. The picture of this engine is not mine.
