[QUOTE="andymarkv, post: 16679526, member: 102900"] I had similar thoughts when I test drove a reg cab long bed 7.3, 4.30 truck, but only at WOT, everywhere else felt great! I understand there is a significant weight difference, but I wonder if the 4.30's actually [I]detract[/I] from unloaded WOT performance? The 4.30's & 10R80 kept the revs right at the redline the whole time it was accelerating....which is perfect for an engine designed to work there, which I imagine the 7.3 [I]in factory tune, [/I]is not. If the stock cam still makes power above the 5500 red line, an aftermarket tune that extends the rev range may make it feel "better"? [/QUOTE]
