You are doing one heck of a job on this truck, I am very impressed!
I just bought a 5.3L/ E4L60 that is one of those DOD motors but have been told by several aftermarket Companys that it is not worth keeping that way. I was told it is not go into 4cyl mode like I thought it would. It only shuts off the 4cyl's for about 1.5sec every 30-45sec. If it shut them off for any longer it would do damage to the cylinders, valves, rings and what ever else. The MPG gain is even lower that the reported 10-15% but for a company like GM it makes a differance for their over all Goverment mandated program so they can bring us toys like the LS7. I am dropping my 5.3L into a 51 Ford F1 that I am building for a shop truck and figured this was the best way to fix a Ford

How much clearance do you have between your front tierod and the Height monitors? I looked at mounted them their but was not felling too comfy with how close it was looking at steering lock and full bump so I mounted them off the frame and Z'd the link.

Also what year did they start the DOD and VVT on the Vortec's?
