The old farm truck we hauled feeder pigs in had an aluminum topper on it with an eye bolt at balance point. we had a self braking block and tackle just for it. it was on or off in 2 minutes including tightening the clamps....

the difference is night and day. it is a whole different way of getting the measurement of the volume of air for the computer the MAF is a much better systome but you only get it on OBD II trucks

And to Nextras, I forget what the difference is between the two. If I remember correctly, the MAF uses actual air temperature readings to get the proper mixture in the combustion chamber while speed density relies more on a table? I don't quite recall. I also seem to remember that the MAF system mixes the fuel and air at a different point in the system than SD, but again I could be horribly wrong. Someone please correct me here.

I forgot to mention. I've got those pictures of the intake box I built (with the cover removed, with the relocated resevoirs and drilled out radiator support for maximum cold air (or at least outside air). From your pictures...it looks like we started with the identical FIPK kit. With some patience, and some careful cardboard stencil work, you should be able to build it no problem.
I'll have to upload the interior pictures later this weekend. They are sitting in the boats locker.
Oh yea..about towing with the E4OD. I've got over 50k miles towing a 22' jet sled (4700lbs with trailer) back and forth from California to Washington. With the bed filled up and a full tank of gas (45 gallon aftermarket tank), I bet the weight was around 5500. This is with the stock 5.0 on the stock tranny cooler. The E4OD (properly maintained of course) does just fine...doesn't burn tranny fluid or overheat. Pulled just fine up the Siskiyou and Cascade mountain ranges. Shift kit helps as well.
When I clean out the boat, I'll post those pics of the inside with the box removed.

air intake systems from an engine's standpoint (written in first person)....
speed density: ok, the TPS is telling me the throttle is this much open, the MAP sensor says i have this much vacuum in the intake manifold, blah, blah, blah, blah, blah..... lemme look up all these values on a chart some Ford engineer wrote way back when (and is probably entirely too conservative)...... OK, here's how much fuel i should be adding to the mix based on how much air i THINK is entering the engine.
MAF: the MAF sensor says EXACTLY this much air is entering the engine. i should therefore add this much more fuel. tada. i'm done.
it gets a little more complicated in newer vehicles with computer-controlled timing (as opposed to a distributor), but you get the idea.
