Little engine syndrome is a lot like little guy syndrome. There's always some need to "prove" something. Now don't get me wrong, I won't ridicule anyone because they chose the 3.6L. If that is good enough for them, great. It's not for me, I always want a V8 if it's available. In fact the only vehicle I have ever owned without a V8 is my 2000 TJ Wrangler, but if they made them with a V8, I'd have one, but I still picked the biggest engine, the 4.0.
Quite some years back on the LX Forums, there was a guy with a Magnum, claiming to frequently dust Hemi's with a stock 3.5 V6. I did then and still do own a Hemi Magnum, and had driven a 3.5 Magnum my brother rented once, and of course there was no comparison. I mean the Hemi had 90 more hp, and 140 more pound feet of torque, yet the model down the food chain was actually faster according to him...uh, yeah OK.
