Is anyone running a 4.7L???

I have one in my 00 Durango. It sounded awesome when I replaced the huge original muffler with a single Flowmaster. When that rusted out, I replaced it with a Walker turbo muffler and the sound is the same. It's quiet while cruising with no droning but it sounds loud when you open it up. The engine likes to rev.

The problem with the 4.7 is that they like to sludge up if they aren't maintained really well. There are very few performance upgrades for them too. I've heard they don't respond well to the typical speed parts you install on other engines.

I thought it would be cool to swap one into an older car just because I've never seen it done. The newer ones have a lot more HP then my 00.(different heads exc...)
