Re: Straight 6 better than V8 in early 50's

The 7X was a LOT more than higher compression. It was a 232 head on the 308, larger valves, VERY deep valve reliefs, a hotter cam, and a LOT of internal massaging done to the crank, lifters and lifter bores, and rods. It really was a special engine, and I'm convinced that some of those tricks can be done on the Packard straight eights.
