I'll take it as you are wanting decent performance. Midrange power will be an issue here. So i'd suggest a cam that provides decent low end torque that emphasizes power between 2000-4500rpm.
Now if you are wanting this for a work truck, you'll need something that puts its emphasis on low end torque.
I can't name cams off the top of my head, because i've never done a swap on a 300 before. but i'm sure there are other folks here that will help you.
Good luck!

I have run both of the Crane cams offered in my 300, the 260 and the 272. I am much happier with the 272 cam. I am running at about 10:1 compression and I had some problems with detonation when I had the 260 cam in. The 272 cured this problem, not to mention a noticeable power increase and actually better fuel mileage. I still have great bottom end torque and smooth idle.

My 300 has 360 FE flat top pistons which are standard size yielding a .050 oversize in the 300 and about 10:1 comp, crane 272 cam, crane roller rockers, offy dual port manifold, 650 cfm holley double pumper carb, trans-dapt swirl torque 1" carb spacer, headman headers, msd adjustable timing control. Centerforce clutch, backed up with a toploader 4 speed. I had the engine assembly balanced and I ported and polished the head I am running with a cast crank and a fine tooth set of timing gears which run much quieter. I have run this engine over 100,000 miles and it's still holding up well I would have to say it has exceeded my expectations. I get anywhere from 15 to 18 mpg. I have this motor installed in my '57 F-100.
I see you are down in Kaispell, I'm not too terribly far away in Balfour, BC just north of Sandpoint.
