We took the opportunity while in the shop to try out a couple of tried-and-true bolt-on performance parts that we had in the office before going directly to the EZ-EFI test.

With the EZ-EFI system making the engine management calls, we saw horsepower rise from 317 to 328 at the wheels, and torque increased slightly as well, going from 378 lb-ft to 382. As we outlined earlier in the article, there are many reasons to consider the EZ-EFI system, and if your needs require more, FAST has you covered.

Old School Power Tricks
Originally for our recent Capri project, this electric fan and pulley set from Latemodel Restoration Supply found its way onto our Street Smart Windsor project as we knew they would produce a healthy bump in power. The aluminum underdrive pulleys (PN ASP-820-125) sell for $104.99, and produced an increase of 8 hp and 11 lb-ft of torque over the factor steel pulleys.

Ditching the stock clutch fan is also a good idea on 5.0L engines, and this budget-friendly electric unit from LRS retails for just $139.99. It comes with its own adjustable thermostat and all of the necessary wiring to install it. The fan (PN PRO-67015) didn't disappoint on the dyno, adding another 8 hp and 7 lb-ft of torque to the Windsor. Tried and true parts that work!
