I have a Flo-Pro V7, its a chambered muffler similar to a Flowmaster. Nice, deep sound. They are made up in Canada and are actually a little cheaper than Flowmaster. The quality is good, nice welds, and after 2 years mine still looks pretty new.

I have super 40's on my truck but if your going for loud Ive herd glass packs do a decent job.

I'm not too fond of glasspacks, especially on an F-Series truck. They can sound just plain awful, like some suburban kid's supped up import. I prefer the Super 40's if I wanted a good muffler that sounded great. Also, Cherry Bomb and Thrush (no glass pack) sound great.

Here is a video of my truck I made just this afternoon.
The muffler is a Flowmaster Delta Flow 40 Series. It is 3" in and out and I built the entire system myself from the manifolds to the tailpipe.
The engine is a SOHC 4.6 from an 02 Mustang GT so a pushrod motor may sound a bit different but probably very similar.
I think it has a nice sound though. The video does not do it justice.

Yeah, I think the glasspacks are not the best choice for a V8. Unless you are looking for just plain loud, and don't care about tone. Chambered mufflers sound way better on V8s. I have been running a glasspack on the Explorer in my sig for 7 or 8 years and really like the way they sound on the 4.0s. They are just plain to damn loud on the V8s.
