What's a good cam to hit low 12's

Thank you for the replies. I forgot to mention it's a 360 magnum engine. So the flat tappet cam is a no.

The powertrax locker is not too bad it does take some getting used to but I only drive the car in nice weather.
I do drive the car in the street whenever I can and on the highway so I'm not going for more gear for now, and I don't want to carve up the trans tunnel for an overdrive trans.
