Possible cam install

I have a bad lifter and am getting ready to swap out the heads at the same I am installing the lifters. I was also looking at installing a new cam. The question is if i can do a cam swap with the engine in the car due to the fact I'm Little limited on space at the moment in the garage. Also what is a good cam selection. The car is a 74 Duster, engine is a 78 318 all stock at the moment except redbrick performer intake a 833 and 3.23 gears The heads will be 360 heads shaved to keep the compression up and port matched with a little polishing probably stock 360 vales.
