Your very close if not right on the money. I cut my boxes 32" long and mount the front floor flange of it directly over the cross brace spot welded in for the radiator support bar. For the 351's I make the boxes 9" tall.
Another tip,,,,,,, Use 5/16th x 1" wide metal strips around the hole area that the boxes will bolt down onto. This way the flange will bolt down onto something that is the same top height of the rest of the ridges without bending it all up!!!! Give it a flat surface that is the same height as those ridges.
I drill a few plug weld holes in between the bolting holes and then plug weld it down like a picture frame. Drill the mounting holes and tack weld 5/16th nuts on the under side at the same time. At the ribs that are sticking up I cut them and then make that area flat in order to allow the new metal strip to lay flush.
Here is a pic to help explain it a little bit better. The cylinder heads are staggered of course but if you start the front flange directly over the flange for that radiator bulkhead it will also give that area strong point to bolt down onto.

I modified my box also...pretty much the same way as Vic.
I also cut in an exhaust port to the bed with a fan, (because I have a pickup).
For some reason, with a Taurus 2 speed fan, the engine was still running hot at highway speeds.
It would cool down just fine at side road speeds under 50 mph.
Here in Jersey if you have to drive at 50 mph all day you might as well walk.
So, that led me to believe there was an air flow problem at high speeds.
So, I've installed a Dodge doghouse. It is a lot wider and taller.
I've cut out a lot more floor than just at the header area.
I'll be putting the seats back in for a test drive before I put the carpet back.
Many guys build that air tunnel when they go to the V8.
Some have built scoops.
I may have to also..
But before I start to cut up the floor again..
I'm going to try a remote fan cooled trans fluid cooler, since I have an automatic.
I have the parts from Jegs just need the inline 180 degree temp sensor.

To run at 50 mph is ridiculous at best. You might as well have the 144 with 4:11 gears in it,, LOL
Curious as to WHY the Taurus setup is not working for you. Did you change over the alternator to one that will let it run a full CFM rating??? If the alternator is not putting out enough then the fan will not work at its best either? How many core radiator do you have (obviously a 240),,, Do you have the belly pan on and is it sealed??? The 3G alternator puts out 90 amps at idle and either the 135 or 150 at stock and even a 200 if you want one.
I have the remains of a 67 pickup here that someone else had don't a hack job to the back of the cab also,, what a hack job and looks terrible. IMO,, you can get the pickup to run cool without doing that.
I have two Dodge doghouses here for sale if anyone is interested, complete units. By far the best unit to use is the Chevy cross flow radiator and it will cool anything. Its larger and goes completely across the front of the truck but needs also the Chevy doghouse which is scarce at best.
I first came up with the remote fan cooled trans cooler about 20 years ago and have installed it in many trucks and cars since then, IT WORKS on any vehicle but even more important on ours with a doghouse issue in the 1st place. Don't know why people don't or didn't try it in the 1st place??? The torque converter works by slipping and slipping causes heat, which added to a compromised cooling setup in the start doesn't make much sense to me.
Sounds perhaps like we are getting back to a situation of where a person is in traffic, with his heater going so as to help the cooling load on the radiator and his foot on the gas pedal to keep the RPM up so that the alternator can put out its maximum of 40 amps????????????? LOL
IMO,,,, run the 3G alternator, the belly pan, open up the doghouse under the seats, a 4 row copper 240 type radiator with the 3G alternator and the remote fan cooled transmission cooler. That would step a person up to a stock late model F series truck from the factory.....
As far as the thermostat for the trans cooler I drill and tap the top of the oil filter holder to mount it and run it hot all the time so that it will continue to cool all of the fluid in the ALUMINUM transmission lines.....
