The intake manifolds themselves are the same (except for the heater core nipple locations), but the difference is most likely in the airbox/silencer/maf/air tube setup. That probably doesnt have much effect on the numbers really. Id say the bigger factors are the tune followed by the exhaust setup.

ok thanks.. just wondering on what to expect after my swap is done. I will be putting in the mark converter since I have one here and I would like to put on the Accufab plenum 75 mm throttle body and kooks headers during the swap if I have the extra cash. Maf will prolly be the factory bird maf and no tune right away, but will be getting it tuned in the spring prolly.

later,

There is zero difference between either a mustang or Explorer engine in our cars (save the 80-lb weight savings on the aluminum Explorer block). Mechanically (performance-wise) they are identical.

Another power gain for the Stang over the Exploder is that the Stang has an e-fan, the Explorer does not (it's belt driven).

Well, it's a truck, not a racecar. The few ponies that are lost turning the fan arent important. Trucks need torque more than horsepower.

Are trying to tell me that a belt driven fan steals 21 hp? Bah!

Prolly exhaust manifold design, and air intake design. I also want to maybe guess that there might be some viscosity drag through windage design. I am sure the Exlorer has a different oil pan(it is a truck), but I am guessing here.

21 hp difference is alot to blame on a belt driven fan. We're talking nearly 10%.

But then again, unless you dyno both engine's in stock form, there is no real way to know if the manufacturer fudged the numbers a bit(like back in the 60's and 70's) to help sales/insurance premiums

Dude when did I say the fan was the only loss? I said another power difference is the fan. Aaron already listed exhaust and tune which are probably the two biggest differences.
