Edelbrock Pro-Flo 4 EFI

Pricing is pretty good. I was going to suggest the MegaSquirt Plug and Play systems that use OEM Ford wiring harnesses. The box is a $1,349 purchase and you source a wiring harness from a salvage yard. The system uses all Ford sensors (or any other sensor you want to take the time to calibrate). You still need to find a manifold and throttle body so you will likely end up about in about the same ball park money-wise. Here is a link to the P-n-P system => MS3Pro PnP

The aspects I found attractive were the ability to run any engine by changing the displacement in the tuning s/w along with multiple engine fail safes to protect the engine from whoopses that cost rebuilds along with the traction control and knock detection and prevention systems.

A big unspoken but obvious positive was the ability to use an OEM Ford wiring harness rather than stringing my own. The OEM harnesses tend to have a very durable construction which is always appreciated and salvage yard pricing is cheap - sometimes as low as zero if you are willing to do the harness removal from the vehicle.

From an ease of use standpoint the ECU comes with a base tune, tuning software and data logging s/w that you can access with your laptop through a blue tooth connection. I think I paid something like $75 for the bluetooth gizmo to allow the laptop to wirelessly connect to the system.

The big drawback is you have to source the manifold and throttle body so the alternative you are looking at adds a very comfortable one stop shopping sort of benefit that is not insignificant.

To the extent possible you want to try to avoid the throttle body injection and go to port injection if at all possible. The port injection gives you a dry manifold so the usual fuel separation as you go around corners (in the manifold) does not occur and it allows you a much broader selection of injectors to choose from for fueling purposes.

p.s. Your pic of the system you are looking at does use port injectors so my comment about throttle body injection is off the mark, the system you are looking at does not use it — my bad.
