360 street car Help

I like the .509 MP cam myself, we've used it in a few motors and it's the next cam for my motor, just make sure if you're running an auto that you have a good, quality stall converter to go with it. The Air Gap is great, but look into the Air Gap offered by a company called I think Competiton Products or maybe Performance Products, some of the magazines have been using it on builds to save bucks and have really liked it.
