I have just read in Four Wheeler Magazine something kinda cool but not sure if I like it. GM has created a 4.5L Duramax without the help of Isuzu. They will still be labeling it Duramax. The thing I am kinda hesitant on is that it is in a half ton. They say it will be relased in 2009. The disturbing news is that this small V8 Duramax will create the same amount of power as a LB7 310 HP and 520 TQ. That is kinda weird hearing a smaller motor will make the same power as a 6.6! Well reply to this and let me know what you guys think!
