Cam Problem!

Bad news. While in the process of taking the Cuda home (for the first time after rebuild) I wiped a lobe out on the camshaft. I am going to replace it this weekend and thought I might try a different cam this time. I was wondering if you guys might would give me some suggestions. These are the specs. The cam I have in it now is a Comp 20-214-4., 270 duration 470 lift. The rest is as follows
.030 over flat top pistons
1.6 roller rockers
Edelbrock Performer heads (63cc)
Dual Plane intake 1500 to 6500
600cfm carb (temp)
TTI Headers and Exhaust
904 Trans and 2500 stall
8 3/4 rear 3.55 gears
275/60-15 tires
We already know the compression is really low on this engine. I will be using it mostly as a street vehicle but like everyone else I want it to sound good and have decent throttle response. I don't want to have to change the converter if at all possible.
Thanks!
