Even if he does post a pic from a magazine it's not going to prove they were ever built that way from the factory as regular production vehicles. Most magazine test cars were pilot cars, many of which had modifications and parts details (not all mods were made at the factory, but rather by the magazines or dealers that recieved them) that never made it into production.....
Here’s a good example of a production engine with parts that never made it onto a production car. Going strictly by the picture, you’d think the manifolds were on every Stage III car built.
