I have a 1985 gt conv auto trans it was the last of the CFI inj carb I think this is the worst piece of crap design ever made the car has never had proper power even after a complete rebuild from the crank up still worthless on power seems it is always starving for gas I don't want to put any money in that fuel system. I want to replace the original intake with the edelbrock performer and holley 600cfm and a fuel regulater then disconnect all the electronic CFI. I'm sure this has been done many before what will be the draw backs? I really noticed the differance when I picked up a 1987 gt 5speed conv 120,000 miles for $3,000 excellent condition obviously garrage kept origanal paint every panel including hood has matching ser#'s the responce time speed and performance is unbelievable

FI can mean one of two things co I will cover both. If you are referring to a forced induction setup, you would have to get a carb bonnet to direct the boost through the carburetor. If you are referring to a Fuel injection application, then no it will not work out of the box. You would either have to weld in injector bungs for the fuel injectors or run an aftermarket efi set up like the FAST EZ-EFI setup that has been release specifically for converting carbureted applications over to fuel injection.

Joseph, you can use several lower intake gaskets to seat that intake to Ford Racing X306 heads, I would suggest Ford Racing M9439G50 with silicone used at the valley walls on the front and aft portions of the intake.

The Ford Racing GT40 "X" cylinder heads are on the smaller side of performance heads and therefore have a somewhat smaller port when compared to most. That being said, I have yet to encounter a street or street/strip intake maniforld that will not work with these heads.
This Performer RPM intake would be a great match when using the GT40 X heads, especially when paired with a good carb and camshaft.
