Mopar's best engines. Your opinion and why.

As you know, I am a advocate for the 235/273 but Mopar built many different engines and it seems that every one of you has their favorite. I have owned a couple 235/273's a 318, a couple 340's, a 361, a bunch of 383's and had the pleasure of flogging a couple 440's and a 426 Hemi's. Speaking just from the HP/cu.in. ratings (I know those HP numbers were tainted in the late 60's-early 70"s) The Charger/Commando 273 is #2 on the list. The #1 engine was the 425/426 Hemi. Now don't beat me up on this, lets just discuss the diferent engines and why you thing they are superior. tmm
