Pick a cam for me

Howdy all. I posted this question some time ago, but i have since made changes. Here is what i have:
78 police 360
Re-ring the original pistons, factory 72 340 intake, thermoquad carb, windage tray, factory heads with 3 angle valve job, 340 valve springs, factory exhaust manifolds, 323 gears, od833 four speed. Looking for 300 hp. Going in a 76 swinger.

also should i get moly rings or standard? Thanks!

I have a lunati 10200701 hydraulic flat tappet in my 318, and it is decent. You may consider the 702, or 703.

Keep in mind that you will probably want to stay with the 702 depending on any need for vacuum, and your highway gears. Also, I bet your compression is probably going to suck if you are sticking with those 70's pistons. At least you will be able to run crappy 87 octane gas

AJ can. Break down the math for you, but it is probably in your own best interests to get some engine math books. If I remember when I get home from work, I'll post up the isbn numbers and links.
