Cam swap ?

Im thinking about swapoing in a new cam.

The motor is a 72 with a stock bottom end as far as i know it still has the low 8.5:1 pistons in it but I think the heads may have been milled alittle.

The currant cam is stock also I think. It idles with a little lope at 800rpm and pulls hard from 2500-6000rpms

The motor has a LD340 intake, Eddy 600 carb (also have a650 double pumper tp try) 1-5/8" headers,MSD ignition. 1.88-1.60valve heads.The trans is a 727 with a 10" conv. and full manual valvebody and there will 4.10s or 4.30s in the rear with a 28" tall tire. The car has been lightend up and wieghs around 3000lbs.

Ive been thinking of trying the CompCams XE268 , XE274 or XE284.

It may one day get some RPM heads but not anytime soon.
What do you think ?
