Thanks Lincoln, that clarifies it. But the same basic principals apply I think. If I were to make the effort of boring a block and machining to accept a different crank I would make every effort to get stuff right. Maybe I'm a lil overkill.. I'm not trying to start an argument with anyone, I only had some questions is all.
The biggest limitation in the Stovebolt is still the cylinder head. Its marginal in breathing and performance even for supporting 235 cubic inches. So adding more cubes often shows little gain in performance compared to other engines with the same mods for the costs involved. As HotRod Lincoln said, it's basically a tractor engine by design. The GMC cylinder head being very similar however, lacks the shortcomings the Stovebolt has, and makes its design more responsive to modern technology and techniques.
