Welcome to the forum. That’s not a bad combo for the engine, it’s just a bad combination for economical driving at sustained freeway speeds.

I’m running 4.10 gears in my 1960 with a 4 speed manual, and 29” tires and spin 3000 at about 60. Using the same calculator site I just drop my tire diameter to 28” to make up for the true rolling radius, and it calculates out to 61 mph at 3,000. The extra 500 rpms is lost in the torque converter. He is probably correct in his statement. For me the setup is ideal, because all of my driving is around town and I almost never take it on the freeway. Whether this is a good fit depends on how you want to use the truck. If it is a good bargain but the drivetrain is a bad combination, it’s a matter of putting on taller rear tires, changing the rear end ratio, or putting in an overdrive transmission.
