? Converter

Shaun might have been mistaken. It would not be the first time (IMO) that he spec'd a more racey convertor for a street car. You have decent gearing (especially with the small tires) and a decent engine. I would think a 9.5" tight with 2200 brake and 2800 flash stall. But...I've had to be VERY specific with him before...lol. If you read about "10 inch" convertors, most use a GM 9.5inch diameter convertor core. So you will see both 9 1/2 and 10 inch units. The MP ones from Manicini are not bad parts either. They would be a good convertor for street cruising. If you street race, that's another story.
