Thanks- I seen the kbb price but wasn't sure if s particular year was any worse or better than others. I wasn't aware of the Heritage series upgrade. I'm taking $5500 with me & hope I'm driving that bad boy home Monday. I'll be on this site more often then. He said he has a bunch of 6.4 upgrades like cold air intake,manifolds but I have to read alot more- thanks for your input!
