Congrats Ben!!
I've been thinking about adding a block heater to mine...I've got the 4.3. From what I've been reading here and other places, this shouldn't be tooooooo awful bad a mod and your tips about the butterflypiece should help out.
Our winters are no where as bad as yours are, but not having to idle warmup for so long would be great. We probably will get as much snow all winter as you had in that first snow pic
