Ok...I've been really thinking hard about waiting till 2010 to get back into the performance sceen. GM is coming out with a 1/2 ton silverado with a 4.5L duramax diesel engine cranking out like 310 HP and 520 ft/lbs. of torque...thats an awesome platform to make a seriously fast truck...add a tune, cold air, and a good exhaust, and we're talking about some major power...and it gets 25 mpg on top of all that! I know I'm committing a huge sin here; talking about a diesel on an LS1 forum but what do you guys think about this?
