What cam to run????

Need suggestions fast:What cam to run????

OK Iam doing my second engine build and want to do it right, but cant seem to decide on the cam.
This is what I am running as of now

All forged 306
Afr 165s with spring and valve upgrades
tublar gt-40 intake with ported and polished lower
1.7 roller rockers
75mm throttle body
75mm bullet mass air
30lb fuel injectors with 255 pump in tank
AFM power pipe
7AL-2 Msd
373 gears
tko 500 tranny

Also what do you think Hp will be on a combo like this?

Ya I kinda figured that was the way to go but I was wanting to see what other people are running to get an idea on lift and duration with AFR 165s.
I am really worried about the lift becouse I dont know how much I can go with speed pro pistons and those heads. People have been telling me that 520 is the max lift i can go. I have stock cam now with 1.7 rr, I dont know what lift that is?
