360 engine build opinions - first engine build

My daughter and I are building her first engine; a 360 to install in our basically stock 73 duster (8-1/4 rear end). Our plans are to install it with a Mopar OD automatic Tranny. This will be a daily driver (dependable), with the occasional trip to the strip(performance). We want to build something with a HS student budget and a nice idle lope and fuel efficiency. So far we have a good solid engine ready to go to the machine shop. I would like suggestions on cams, pistons, rebuild kits, carb, manifold, heads, torque converter... Any help would be appreciated, I'll post pictures when we're done.
