Huge image, sorry 'bout that...... This is a double roller timing set. The stock flavor is the morse style chain, that is just flat links, no rollers at all. They tend to stretch, and with the mileage on yours, I suspect you will feel a MAJOR improvement in how it runs/feels.

Hello again and thank you for that info.

I will deff have to look into that. I am guessin that I would also have lots of wear etc. I don't have any knock or noise or excessively rough idle that I have noticed.

thanks again tho

Biggest problem is the chain stretching, throwing off ignition and cam timing. Basically, you lose a fair bit of power/efficiency. It's a job to change...... and be careful with the oil pan gasket, else you'll be dropping the pan as well.

I was just hoping an aftermarket intake would help solve the plenum issue as well as perhaps give me slightly better gas mileage. Cause I think my plenum is leaking too I think.

Yah I had an '04 magnum with the hemi in it and it was brutal on fuel too but not quite as bad *laughs* love the truck tho...

Also for clarification when I said "carb" i meant intake throttle.

As for plugs and O2 I have done em in last yr. I have some more I gotta do (like pass front wheel bearing, shocks etc) and aluminum rims instead of steelies. But I appreciate the help!

I am getting about 18.9L/100km or 400km to a full tank.
Don't know the conversions. I am not expecting ever to get even 16L/100km but even 18.4L would be great!

thanks again everyone!

No 2002 hemi, came out mid 2003. The only problems the early 5.7's had was a few random valvespring breaks and if you overheated it enough (alot) you could drop a valve seat. Better than substandard cam cores and crappy lifters (2011-2015).
Magnum's were introduced in 2004 but it was a 2005 model year. I have an early build Magnum. It will get decent mileage.......IF you keep your foot out of it.
Say what you mean and mean what you say....a throttle body isn't remotely the same as a carb and it matters when asking for advice.

I'm not sure what hemi issues you are talking about directly. to me the 03-04 hemi was the best of them all (there was no 02 hemi), maybe the eagle head engines are comparable, only because better heads to offset the poor cam n lifter design. The biggest down fall to the hemi or any pentastar motor is do not idle them, and 5w-20 is to light of oil.

My 1500 mega will average 15mpg or closer to the 16l/100km you desire on the highway, 13mpg daily driving and that's rolling around a 5000-6000 truck on 34" tires.
I agree with the oil, but there is nothing wrong with the design per se, it just seems that way when some bean counter cheaps out on important components (cam cores and lifters). The lifter issue wasn't a thing until about 2011. Someone cut open original 6.1 lifters, an eagle lifter and then a 2015+ lifter; the needle bearing differences were astounding.
