Hi Guys

I've been reading through the thread for a few days now trying to soak up as much info as I can. I'm looking at buying an all ready converted GU with the turboed 6.5 + 4L85E. Apart from overheating issues, is there anything in particular that I need to be looking for with these engines? Apparently the one that I am looking at has recently had the injectors replaced. Is that something of a concern?

Cheers
Adam
