Spent a week on the Canary Islands, just drinking beer and reading, so I got thru the Hemi book, (and about 30 Mopar magazines that I had on my iPad) it actually was not bad, but released in 2007 it had no info on the electronics, computer and sensors etc. Everytime something was mentioned about it, they just said that there was no info on this yet and soon they will crack the codes for the computer. It did have a lot of mechanical info on the 5.7 and 6.1. Since it was a cheap book, it was still worth it for me, I got some good info out of it. I'm sure some folks here has a lot more knowledge about the Hemis, as I read some of the threads here. Anyways, I am now convinced that the Gen III Hemis are great engines, and eventually one will find its way under my hood someday. Maybe by the time I'm ready the Hellcat Hemi is available, would be nice. Until then I'm hunting more info.
