Down to 2 cams

Another cam decision:

I have a 1973 360LA bored .30, zero decked 9.5-1 comp. KB 107 pistons, stock crank, J heads (2.02-1.60) ported, comp 901-16 springs, 273 adjustable rockers. RPM Air Gap, Holley 750. Converter 2500-2800 stall. Currently stock 360 manifolds but Dougs headers in future. Rear end 3.55

The choice comes down to 2 cams.

1. Comp xtreme energy 268.

2. Comp xtreme lift 275.

I am leaning 275 but I worry about going too big with the cam. This is going to be a weekly driver. Maybe a few trips to the track in her life but almost exclusively a street car.

Any thoughts are appreciated. I need all the help I can get!
