Clutch Recommendation

[Admiral]

I'm working on building an engine for my '51 Crestliner. It will have a 4-inch crank, a mild overbore, probably EAB heads for an extra shot of compression and an Isky 1007B camshaft. I will also run it with overdrive. Will the stock, 9.5-inch clutch be able to handle the extra torque of this setup or should I plan on getting a larger clutch? If something bigger is recommended, what style/size should I look for?
