Choose my cam and intake!

Hello fellow Mopar friends! My name is Roy(23) and I am in the process of getting my 68 Charger all freshened up. My car is an original 318 and I just recently purchased a 440 witch was rebuilt.(possible standard bore and compression) well the previous owner said that the guy who had it may have put a cam in it but I don't know. I bought the engine COMPLETE came with eddy 1411 750 and eddy performer 440 non RPM.

block numbers are 4006630-440-10, the heads are 516's and have less than 100 miles on a fresh rebuilt, but I will not be using these heads i have purchased some (0 miles) 906's(2843906) with the following modifications: Ports and pockets ported out full length, multi angle valve job blended stock 2.08 intake and ex 1.74 valves reground seats factory stock, seals replaced, new hp springs good to .575 lift, 130 psi seat press 330 at .500, lift deck milled .020 open chamber 82 cc.

Now I want a cam that will take advantage of the heads at that max lift, I have a rebuilt 727(3k converter), car will have 3.55 gears in the 8 3/4. as for carburetor, I will be going with the new FAST EZ EFI KIT i was thinking of going with a Edelbrock Torker II.

Thanks guys, I would appreciate the help! =)

Before you start picking out cams you need to know what your compression is. Stock compression can vary from 10.5:1 to 8:1. What pistons are in it? How far down in the hole are they? Your block number according to my info is a late 70's unit and those are low compression. If it's rebuilt stock chances are it's built to 77-ish specs. Also, you will give up roughly a half point of compression going from the 516 head to the 906, which may be a step in the wrong direction. I didn't see a mention of hard seats. You will need that done to run reliably on unleaded gas.

Take a good hard look at your parts combination including the condition of the 516 heads. Those might turn out to be your best friend because of the added compression (assuming your pistons are deep in the hole), plus they might even have hard seats installed and a 1.74" exhaust valve upgrade.
