I had several 3.5 EB trucks and one with a 5.0 V8. The 5.0 is marginally slower in my opinion. At work we have a 2wd single cab with a NA V6 (standard engine), although it isn't as quick as the other two I wouldn't label it slow. I have also driven a truck with the 2.7 EB which was pretty quick.
Bottom line is none of them are slow.

I've seen lots of people confusing ply, load rating or LT and in actuality the only thing you need to consider is Load rating. Manufacturers only rate there tires in ply because we as consumers demand it. There are practically zero 10 ply tires out there....even the ones that say 10 ply are not 10 ply. Along time ago it ment something perhaps back during the bias ply days or shortly after. Now the ply rating is completely subjective as to how HD the company wants us to believe there tires are.
At most a LT, E rated or 10 ply tire will only actually have 6 or 7 ply....I say or 7 because there is probably some off the wall tire manufacturer I never heard of who has done it and I'm sure someone will find it.
My (Wild country) tires are only 6 ply and they are E rated....they simply chose not to inflate there ply rating so that the (wild country atr) would still sell.
In closing rules may vary in your area (perhaps your legislation is 40 years behind) but unless you run commercially there's no need to pay for LT or 10 ply as long as the load rating is correct.
And yes to the OP. You will notice a big improvement with tires that are in the proper load range

(and yes, I'm driving around on "10-ply-rated", three-ply construction tires, which threw me for a loop and led to my personal opinion that we should stop using the "ply rating" entirely when talking about tires, but I doubt that will ever happen)

While ply ratings are not true to the actual number of ply’s I can tell you that it does matter when pulling a trailer on curvy roads. My original p rated tires which were actually st rated tires have a max pressure of 51 psi and just about the same weight rating as my LT C rated tires which are rated for a max pressure of 50 psi, but there is a huge difference between them when towing. The best way to describe the difference would be not as squishy or better yet much more precise handling meaning on narrow, windy roads when I turn the wheel it turns when I need it to not a few feet further.

Trailer tires (ST) are a different animal. The sidewalls are designed for twisting and scrubbing. A P rated or LT tire sidewall could fail when used on a trailer, so keep that in mind when tire shopping.
Those LT tires that came on mine, and the BFG Advantage TA tires have the exact same load rating.

Passenger Tires
Since most P-metric passenger tires are manufactured in the standard load range, they will have nothing branded on their sidewalls or may be branded standard load and identified by an SL in their descriptions, as in P235/75R-15 SL.
