Hmmm?

Maybe you should understand what you\'re posting before chastising me. It\'s ok, I\'ll help you out.

First, no vehicle other than one manufactured by Honda has VTEC®. That is Honda\'s registered name for their variable valve timing technology. Therefore my statement was true on that basis alone.
Second, I can almost guarantee you that the H2 does not have any sort of variable valve timing.

They put "OHV" in the specs, which I guess implies that it\'s not a pushrod engine, but it still has only two valves per cylinder. It seems pointless to implement variable valve timing on an engine with two valves per cylinder, but even if they did, don\'t you think they would have mentioned it? I\'ve been looking everywhere, and found nothing. I\'m sick of looking for more tech specs on this engine, but you can keep searching if you want. It seems no one cares enough to bother talking about it, even on the Hummer forums.
BTW, it\'s just another boring powerplant found in any number of GM SUVs and trucks. 316hp out of a
6 Liter V8 is pathetic. My F20C makes 240hp out of 2 liters and four cylinders.
