People here have given good advice.
The great thing about the later Explorer engines with the GT-40P heads is the greater air flow through the heads while not losing any velocity. And while the swap is a good idea, here are some good ideas to make a great combination that will really run well together and take full advantage of the better heads:
A GT-40, Cobra, Explorer, Edelbrock Performer or Trick Flow Street Heat intake. While I think there is a chance the new
BBK SSI series intake will out perform any of the ones I've mentioned in this application, it won't fit under the stock hood and will require the Cobra R cowl. While many people choose to put a larger throttle body on their motors, the fact is, when tested, the factory 60mm performs well enough on a 5.0 that it can match a 65mm up to 330 horses and give you better throttle response and easier throttle modulation while driving. The stock MAF can also flow fine for this application so long as the injector combination is tuned in with a chip or aftermarket computer. But grab a
K&N air filter. Many people have their favorite versions of aftermarket MAFs if that is a way you would like to go Two of the more popular brands are Pro-M and C&L. 24lb injectors are a good idea as well.
A Crane 2031 cam, a Ford Racing E303, Comp XE264HR or Comp XE266HR are all excellent choices with matching valve springs.
MAC 1 5/8" shorty headers for GT-40P heads in a '94-'95 Mustang will do the job well and as far as I know are the only ones available for the application.
Your choice of 2.5" H or X-pipe and catback. It's hard to go wrong where performance is concerned. Noise levels and tones will be different with different systems.
A different set of gears. 3.27:1 will allow you to trap the quarter mile perfectly in third gear, 4.30:1 will be perfect for 4th, but many people like street driving with 3.55:1 or 3.73:1 gear sets.
Also, make sure you have the combo tuned by a dyno tuner that can perform the whole gamut of driving functionality from idle, part throttle to full power. This is really where great strides in power, driveability and functionality can be found. But this in no way is an exhaustive explanation of what would be needed to make the combination work.

As far as I know the mayor differences between a mustang block and an explorer block is, crankshaft and heads. Does any body have more info on this, for example which one is inclined to have more torque and which one is inclined to have more HP? forgive me if I sound dum but I am new to all this. I would really appreciate any more comparison info.
Thanks
