Got a few questions for the engine experts: I’m looking at a 2006 Magnum R/T as a family hauler (In addition to my Challenger). What were the major differences (besides the 340hp) between 2006 and current 5.7L Hemis? Did they have MDS and Variable cam timing back then? Were those pre Eagle heads? If so, does most of the power difference come from the newer heads? Or can I make up a lot of that with a tune? I know we’re a Challenger page, but if anyone has any other info on what to look out for on a Magnum, I’d appreciate it.
