Startup rattle

[Mag05]

I use a company van so my Mag sits most of the week, usually 5-6 days, so when I start the car there is a quick rattle. I believe this is the roller lifters, which is not a problem but the issue is with the tune in the car that I have, initial rpm rev up on start is 2100 rpm. I maybe alittle paranoid about this, so I am wondering if there is a delay spark module available, or it's just me, no worries? Anyone? Thanx, Cal

I don't think you need worry. Our motors are kinda loud anyway. If you use good oil, I use Mobil 1 or Castrol Syntec and change it at regular intervals. If it's not throwing a CEL, I'd guess it's just a hemi doing it's thing. My motor got quite a bit louder after the Sidewinder cam install. Made me a bit nervous. Everybody that hears it , however thinks it sounds great! Oh yea, 146,000 miles on mine , still uses no oil!
