That engine bay looks great but there are several things that are not 100% "correct" in a truck. The truck engines were not orange, they were a blueish green. The valve covers should be the Chevrolet script. The upper radiator "hose" should have a steel tube connected at each end with short rubber hose. The AC compressor brackets aren't the correct truck items. Truck brackets were all stamped steel. The brackets used on this engine are the type used on '64-'68 Chevrolet cars and '68-'72 trucks.
I really like the "327" valve covers and the orange paint. Seems a Chevy engine should be orange. I'd do same thing plus a few other changes using all OEM Chevrolet items to spice up the engine bay. Factory chrome air cleaners and Corvette valve covers look at home on most any small block Chevy!
1967 was the last year for the script valve covers. In 1968, engine castings were changed. The PCV vent hole at the back of the block was eliminated. The PCV system was changed and was vented out of the valve cover and air cleaner. This change made it difficult to use earlier non-vented valve covers on post '67 engines.
