that bel-aire would be perfect, you will be in a whole new world of air!!
i have a bel aire, the 7.5 hp model, 24 cfm @90 psi, runs 3 spots easy, but i have 1-1/4 hard line also, anyway i would seriously look into either a compressor or renting a booth, you could esily do whole car in one day, just bake the base for a few, and then tape stripes and put main color on, the untape and clear everything 3 coats
