I wish i had that blk, i'd love to build a blown alcohol b/blk. O'k back to your question, i donot think the cam is a good choice for a blower motor. It's a real stump puller for a normally asperated 500" motor single carb, if you're talking about the normal .714/.714 cams that a lot of b/blk guys are running. If you're talking about a special blower grind, forget about what i just said, but i've never seen an equal lift or duration blower cam.
