Right, the Shelbys are a far better block (dual crossbolts, better oiling system, three ribs across valley like a Donovan, improved durability, etc). But for restoration guys who simply want old fashioned tech, the Genesis may appeal, once it becomes up to the same standards and quality as the original sideoiler.
