when you say "difficulty starting", do you mean slow cranking or long crank time before it fires up?
730 CCA is plenty for a stock 5.7L.

Battery
Sometimes my Magnum has difficulty starting in cold weather...so i was thinking it could be the battery. The battery in there now has 730 cold cranking amps...is that enough? I'm in Rochester, and temps have been teens-30's the past couple weeks. usually it has a harder time starting when it's closer to the teens. other than the start problem, everything seems to be running just fine, no codes or weird noises.

i'll start by saying that the starter was not designed to crank the engine for "a min or two". 15 consecutive seconds is about the maximum you should let it crank before giving it a 30 second break.rochester NY...the EVIC shows 14.5 volts so the battery is still good. the times that it does not start up, its about a min or two of holding the key in the "start" position, and it doesnt fire up. its just a lot of starter motor whine and thats it, until the HEMI finally starts.
that being said, you might need to check fuel pressure for slow build up and quick leak down.
