The color of most , and most being the key word, Chevrolet v-8's in '67 was a little redder than the photo. That time frame seems to be when Chevrolet was transforming the shade of red used on their engines. My personal '67 El Camino purchased new had a 396 engine and the color was somewhat darker than your photo of what looks like a nicely restored engine. BY the '68 year model run the engines started to get a little brighter and just a touch more Orange to the color. The finish also transitioned from an almost flat finish to not quite a semi gloss finish not as shinny as the photo. This is based on the vehicles I have owned and it is possible that others had a different experience with theirs. The Big Block engines, 396, 402, 427, were built in the same engine plant and should in theory be all the same color. Most people would never call you on your engine if you wanted to paint it to match the photo. I think it all depends on if you're going for a 100 % showroom stock or a day two type build. I would only suggest you maybe knock down the shine a little when painting a rough iron casting like an engine.
