Small update. Still finishing up some of the wiring and waiting for some larger split loom to arrive. Installed my Speedhut gauges this weekend. Been driving it around and have probably put ~300 miles on it so far.
A few observations:
#1: Sound deadening is an absolute must. It is way too loud inside the truck now. Part of that is the worn out front tires but it needs to be quieter all the way around.
#2: Acceleration is as good, if not better, than the 454, even at light throttle. I was worried about the Cummins making the truck sluggish to get moving but it is excellent.
#3: Regearing is mandatory. The 4.10 gears are terrible. I'm in 5th gear by 40mph. I don't have a tach hooked up yet but the engine sounds like it's screaming at 55+. Likely going to go to a 3.42:1 ratio.
#4: The AFCLive from Power Driven Diesel is great. It really gives gives you the ability to tune this power on-the-fly. Rolling coal isn't an issue. I mounted the AFCLive in the dash cubby. It has a "party mode" switch on the right side so I biased it to the left.
#5: MPGs seem to be dramatically higher than the 454. It's too early to have conclusive data but it seems like this thing will go days on a 1/4 tank. I'll update when I have more data.
So far I'm pretty happy. I can't wait to hook this thing up to my camper and see how it does. I might try that after work one day this week. I'm still battling a couple rattles I can't figure out and it looks like I need to order a new alternator. The engine is loud enough to be annoying but I'm hoping once I get some sound deadening in the truck it will be better inside.
More to follow.
