If I recall, I had just over 100K miles on my 2005 SS monte when I did a ZZP upgrade. I still have the original intake, fuel rail, lifters, valve springs, cam, & roller timing chain / gears... Also have the original Cold Air Intake available.
If anyone is interested in some or all of these send me a PM with an offer and your address so that I can calculate shipping. I won't refuse any *reasonable* offer, I'm also checking back with ZZP I think they were looking for fuel rails and the intake for rebuilding...
Thanks!
