That's correct for the tanks having extra room for more rows of tubes. That
way they can use one tank to fit the "standard"  (1 or 2 row) and "Heavy
Duty (3 row) rads. BUT the more rows of tubes the less efficient the back
rows are due to heat from the front rows flowing over them. SO a bigger
surface area rad is better than more rows,,, IF you have the room. But an
extra row can't hurt, just don't look for it to increase efficiency as much
as the first two rows.

REMEMBER,,, more horsepower= MORE HEAT. ALWAYS better to have too much
cooling than to little. 

I'd be willing to bet with a price like that it's an "imported" rad. If you
look close at the import rads they tend to have more room between the fins
than the OE rads. Which means they have less surface area to cool with.
Something to watch for.

I ALWAYS replace rads with rebuilt engines. It's just NOT worth the damage
done when you run a newly rebuilt engine hot. They do NOT like THAT!

But hey,,, that's just me!
