crate gm 350 upgrades

Has anybody used Edelbrock cam number 7102?  What do you think of it?

I am in the process of building a new motor for my 81. I started with a block and crank from a 69 chevlle. I put a comp cam 268 xtreme part number CL12-242-2. I am using the original heads with 1.5 ratio roller rockers. I am going to use a Edelbrock performer rpm intake and 600 cfm carb. The intake is a little large for my setup, but it was free and will work. A friend put all that info in some program and I should get a little over 300hp from this setup.
