if you do the math and run a 5488 at 3500 rpm Over 2800. with 20.8 tires. You get a 20% speed increase that gets you 3.7 on the 18.5 so about 22.2 mph. 4000 rpm gets you 6.2 mph more so still not 25 mph maybe at 5000 rpm

My 54 is slow on 18.4 42. Not even quite 20mph.

Or maybe his diff, like his engine, isn’t stock............

Edit—I’ve seen his 5488 going down the road, I’m pretty sure his numbers are accurate.

20.8 by what?

20.8-38 is the same as 18.4-42

20.8-42 is the same as 18.4-46

20.8-46 is the same as 18.4-50

We went from 18-46 to 20.8-46 on a 7250 and went from 22-27 mph

Back in my shelling days we shelled for a guy that hauled with pickups and wagons. His words were 25 mph loaded going to town and 45 mph coming home empty.

Also in my shelling days we had a husk or leaf wagon. It was built on a Westendorf gear. Pulled behind the trucks and usually around 40 mph. It never bothered.

Never had a 56,66 or 86 that didn't go 25 mph. 14's on 20.8's at factory rpms will run over 25 easy. So if yours don't go 25 you ain't runnin' factory rpms, your slow. My 5288 goes 23 mph on 18.4 42's. i don't know where they got that 18.5 in the chart, that isn't at high idle down the road.
