What class? The Gen 1 Raptor was a class of 1.
As for the 6.2, mine's been pumping out 570+ rwhp (on ~115 pound wheel/tire combo) for 5 years now without a hitch. Still doesn't even burn any oil. Just has a Whipple with full exhaust and a very conservative canned tune. It was that easy. Power/dollar value extremely high. The trophy truck sound is really just a bonus. And the best part is the truck has never had to go back to the dealership. Not once. Definitely one of the best vehicles I have ever owned.
But I do plan to add a newer one to the stable one of these days. Variety is the spice of life, after all. I am just waiting to see if Ford is going to answer the TRX with a Gen 2.5 first. If not, I will buy a clean 2017/2018 and Gen 3 Coyote/Whipple/10 speed swap it. I expect it will really scoot with that light weight body and 10 speed. I will have to get used to the relatively uncomfortable seats and the loss of low end torque (my 6.2 is a beast), of course, but every truck has its compromises. And those Coyotes sound absolutely amazing at 7500+ RPM. Plus I do really dig the boxy aluminum body. It will look ever better with bigger fenders and bedsides.
