Mainly street driven,thanks.

It depends on what you want to do with the car. If it was mine I would look for a hydraulic flat tappet around or below .5" lift and 220-240 degrees @.050 with an lsa not less than 110.

I am far from an expert- if you're serious about getting the most from your combo call a good cam grinder.

Also think about what kind of torque converter you will need to run to match the cam and think about matching the cam to your compression too. Don't go too radical with the duration and 3.55 gears.

Comp XE268 is a good one. Sounds nice, makes good power, no problems in my 360 with A/C, Auto, and 175k converter. It'll like that 3.54 gear too.

Voodoo 268 grind, Lunati #60403.

Comp XE268 or 274H are good as well.
