yah, that engine is likely the origin point for both the 1961 215ci SBB ( it's an all alum design ) as well as the the Nail layout.
the article is kind of weird in that it misses the primary point of the Nail design, being narrow enough to easily mount in a chassis designed for a straight 8. that's why Buick dropped the outboard exhaust valves and straight ports, to keep the engine package from getting too wide.
also, he says the engine was a '216ci'. i was under the impression that it actually was 215, just like the 1961 engine. i don't think i've ever seen bore/stroke specs on the XP300 engine though, so i can't verify that. i'd also be interested to know the bore spacing and deck height.
