Hi George,
The engine has a stroker crank, probably 3.750. I don't have the engine fully disassembled yet and can't see the stampings on the crank journal. The stroker crank is why he thinks it needs dished pistons. The plan is to bring the needed parts into the shop and then he will figure out how to get the correct compression for pump gas.
I was equally amazed that Clay Smith Engineering is still in business. I am also very fortunate that they are 8 miles from my house. There were three generations of family members in there working away and the business seemed alive and well.
