Nice Vid. Now, can you advance ignition timing on these engines?

[walshmonster2005]

@mrRhwalden There is a sticker on the front of the truck that states you cannot advance the ignition timing. Government Motors says the timing is computer controlled, but I am sure if I had the right tools I could advance the timing somehow.

Why does smoke come out of the throttle body when you open it after you shut down the engine?

[walshmonster2005]

@racedriver52 Unburnt hydrocarbons and a little bit of exhaust.

I was wondering that myself! I've been curious if it's just fuel vapor and if a lighter would prove it

Wow, I have never seen those injectors in action. Pretty cool!

Seems like a fairly simple design too, easy to work on Id think.

That doesn't look like a Hendrickson to me.

Good video - never saw the jets in action with the cover off before!
