From what I have seen just from poking around my engine bay all the time, most of the larger hoses connect using the spring-loaded clamps and some have other special type clamps.
I'd be careful about actually replacing some of those type hoses such as the two large hoses near the PCV valve which are the inlet and out take hoses for the heat inside the cabin. I'd go with something that just slips over them and use a clamp to either secure them or cut them long enough so that they don't slide back and forth.
Good luck on finding a radiator hose that will fit our V6's. I haven't found one yet, but I may just be looking at all the wrong websites. A hose such a this, that's is a big-ass hose, sitting right up front for all to see when the hood is popped, would best look chromed and made of metal.
You can also do other engine dress up stuff like strut covers, fuse cover, battery box, even cover the fender panel screws with dress up knobs.
Poke around
www.50resto.com and
www.uprproducts.com as well for stuff. Some stuff you might actually want to send out to get chromed such as the metal hoses. Other things you might just want to paint some anodized color provided it is heat resistant.
Check arounf these boards as well, someone has a maxed out chrome engine bay that is a bright as staring into the sun with a magnifying glass! He should be able to help out.
