Don't worry about the engine size.
I came from riding motorcycles for a decade, and let me tell you any notion of speed in a truck (especially in today's world) is ridiculous.
The V8 of my year made an extra 50 HP. Like V6 =175 hp up to 225hp V8.
Both are laughable as far as speed are concerned in the larger scheme of things... especially against my old sportbike that did 0-60 in 3 seconds or against a new 750hp sport-car today.
Basically, what I'm saying is, love what you got for what it is. Don't let the "Mo Powa" V8 guys let you feel less-than. Even their mediocre gain in power is laughable in the larger scheme of things.
If it helps - just take off the V6 badging (as I did) so people can't judge.
