EFI VF3 Install
I realize that a lot of people already have VF3's, but I thought I would post some pictures as I installed VF3's on a 2004 1300 EFI. These came from Carl at Island Racing
First thing is checking the fit of the reed stuffers. Usually, they need some grinding and filing for a proper fit. The first picture shows how the reed stuffers did not fit properly. The second and third picture shows the reed stuffers after some dremel work. The fourth picture shows a proper fit with the EFI plate.

After getting the reed stuffers to match the port openings, next is sanding them down so they are flush with the mounting plate. I started with 120, 200 and 400 grit sand paper. I also used a straight edge to ensure the reeds were flush with the mounting plate.

Once the reeds were smooth and flush with the mountung plate, it was time to mount them. The first picture shows the parts needed to complete the install. The gasket to the right of the first picture was created by using a razor blade to cut out around the reeds. The part number for the stock gasket is shown in the second picture.

Carl send me 6x50mm bolts to mount everything. There are four 6x45mm factory bolts that I used also. One trick that I used from my days installing headers in 289/302 Mustangs was to buy two 6x70mm bolts. These helped me align everything as I got started. Just cut the heads off the 6.70mm bolts and dress them with a grinder. Screw them into the upper and lower holes that use the 6x45mm bolts. These two bolts act as studs that align everything as you install them. Once you get the other bolts started, simply remove them. This is a quick way to keep all of the plates and gaskets from moving as you install them.

I used copper gasket spray to make sure that I didn't have any leaks. This picture shows everything installed, which was gasket -> reed plate -> gasket -> stock EFI plate -> gasket -> EFI Balance Plate -> EFI Throttle body joint. I torqued them down to factory specs.

Nice Gator. Hey,looks like you snaped a muffler stay bolt off on #3.Or is it just the pic? Very good illustration on the reed install.One thing to add to this is the use of copper coat or 3m1211 on the exhaust manifold gasket.They are prone to leak there also.

All in all, this only took a couple of hours. I spent a lot of that time making sure the reeds fit properly. As Fercho suggested, I used a piece of glass and sandpaper to make sure everything was flush.
Using the two bolts as studs to start everything really helped, I only needed two hands to put everything back together.
The final install:

What kind of power increase can you expect with the VF3's? Do you need the EFI controller?
