Well my take on the 6.0 vs the 5.3 is this... I don't mind the HP diffrence, I have a toy that runs in the 9's in the 1/4, top end is well over 190mph and is a blast.
The truck is for me, I love the style and look of this truck. You just don't see many of them and I love it that way.
If you want one to race with and all, that is great, I do not mind sitting back in my truck and watching yall play...
Congrats on the new ride...
