I just bought a 07 Classic LBZ with 200k, when i bought it every thing sounded good but then i came to find out that one of the batteries was crap and my alternator was trying to charge it which caused it to over heat up to 300 degrees F and blow some thing inside probably part of the voltage regulator because it would not put out more then 12v tell she got back up to 300 F and wouldn't keep a stable voltage. Well changed battery and alternator and its all good. Getting about 20mpg when i drove it up from dallas. I was hauling *** too. Quad cab long bed 4x4. Weighed in at 7400 on the cat scale with a full tank of gas.

 

Got the duramax finally, it has 4" straight pipe cold air intake and efi live, runs like a bad out of hell and the trans slips just a little mainly in higher gears, what are some other upgrades I can do to it besides trans, I plan on getting a built one eventually

 

congrats on the truck! keep the efi and look into finding a good tuner to help you out unless you feel like tinkering on the computer alot. efi is the top as far as any program for this trucks as of yet.

 

i also am looking at an 06 cheby 3500hd. 4x4 crew cab dually. full leather, dvd, all the fancy bells and whistles. all stock with 82000 miles on it. they are asking 30000. if trade in on my 02 is good enough i am gona try my hardest to get it.

 

Main Problem is.........It will never be a dodge!

 

congrats!!!!!

and to the guy with the 12v i feel your pain when it comes to having a truck that smokes like crazy and having the same dyno numbers as a ford fiesta ........my first truck was a 1st gen cummins...... then i grew up and went to a duramax
