Pick my cam?

Believe it or not, I like the Mopar Performance .528 solid here. It's a fantastic cam and since it is ground on a 112, it will have balls to pull the OD transmission with minimal downshifting. If you are building a high performance Mopar engine, an adjustable valve train should be on your list anyway. The 273 rockers are available very reasonable and there are usually some for sale here. I think you would be really happy with that cam choice.
