Its cast iron and open on the bottom and I plan on using it on my sbc(350)swap in my 59 3600. By any chance would you know what clutch setup I would need for the conversion. The original setup on my 6 cyl is a diaphram pressure plate with a 11 inch disc. I plan on using an 11 inch setup with the sbc to match the flywheel I purchased with the cast iron bellhousing.
