Sounds like an interesting subject, the economy series is usually 400ish hp. It’s usually attached to an automatic transmission and has 260 rears behind that because they are bought by companies like j.b. Hunt, Ryder, Werner, swift, and Penske, they get 500-700k put on them and then are sold to guys that swear they got a good deal because they bought a lugged to death 500,000 mile truck for 50,000$. And on top of it you really don’t see a gain in mpgs because the transmission is driving the truck for you and shifting at 12-1300 rpm’s so either engine you look at is still gonna get 6.5 ish mpgs. It’s a complete waste of money in my personal opinion. The performance series usually…. Usually is a minimum of 535 hp to a max 635 hp factory and could be in any truck with any transmission and any rears and would be bought by anyone except these big companies. The way I see it if you want a 400hp engine why waste the money on a 15 liter?

That may not answer your question but at least now you have an opinion. Whether it’s a good one or bad one lol.
