Mopar P4452761 Camshaft

I have the 761 cam in a 360 that's in my Challenger conv. It runs great, has a little choppy idle, but my power brakes work fine. I have another 761 cam new in the box that I bought from a member here, and have wondered how well it would work in a 273 that I'm going to build for my 65 Barracuda?
