TA rules requre 305 engines.....stroke was more like 2.96 inches..

Yep, and they used a special, longer, "Hemi footprint" rod. At 6.36", people confuse them for "B" 383 rods, but they are .984" pin eyes and 2.125"-bearing big ends. I think they may have used a regular 340 piston cut down a tad, but positive deck to enter the combustion chamber of the T/A heads.
