And Joey D (6. 5 owner), you need to read more carefully and report the actual facts, and not embellish. I had estimated the load to be around 4000lbs not 5000. BTW hows your mileage? let me guess the only reason you have 4. 10's is because you tow sooooo much weight on a regular basis. how bout some dyno or track results? see my sig if you would like FACTS on mileage or HP. or email me and I will be glad to share my spreadsheet and reciepts with you.
Joey D, I would pull you silly, and then pull you, unwillingly, back to where you came from. next time I'll have the wife hang out the window and video the event, as we smoke its doors off. would that be enough proof for you? or should I get it hermetically sealed and notarized too
Pardon the above venting, I was not about to pay $19. 95 to reply to him over there, since I know he's reading this.
as for their comments, I concure. I agree with D Max-Man. I too would like to see proof of anything that is to be rumored to fail. and to-date, I have only HEARD of these supposed "head gasket failures". I also think that a healthy exchange of that or any other information is important. to possibly head off a problem with another owner, before they too have traveled that road. I think the TDR and its membership have done a good job of that here. and from that, we have learned the limitations and gotcha's associated with the use and modification of our trucks.
we have a member of our club here in Illinois Mark G. who has been wide open with his mods and trails and tribulations of his new 2001 Duramax/Allison. To date he has chipped it, put on a new highflow exhaust system and LP. I was quite impressed with his truck when it was stock. he turned out 240HP on the dyno STOCK. and even more now that he has tweaked it.
but, I still am not scared of it. I know, where he's weakest. and that, Joey D, is on the big end. sorry Mark.
BTW: have you noticed about half the new GM's have a light burned out already? I would like to be a DRL lightbulb salesman. LOL
