Include

[mbot]

I have an 05 Duramax that I am trying to get out from under (nothing but probs) and have found a clean 03 Excursion with a V10.

I know the 05+ V10 is more desirable because it has the Torqueshift trans and more power, correct?

Is the spark plug blowout issue PREVENTABLE on the 03?? How can I tell if the truck has already had a plug blowout that was repaired with a Helicoil??

Any help appreciated!!

Thanks, Ben
