The physical dimesions of the Bosch EV6 / LS1 injector are listed in our ad here: http://www.racetronix.com/12561462RFM.html
Most of our ads list injector dimesions.

These work well in a lightly modified LT4:

[QUOTE=Racetronix]The clips prevent the fuel injector from getting ripped off the rail in the event of an accident.
.....That has to be the most hilarious reason I have ever heard for the injector clips. If the vehicle was in an accident serious enough to break the bolts that hold the fuel rail to the manifold, the last thing anyone would have to worry about would be the clips preventing the injectors from being "ripped" off the rail.
The actual reason for the clips was to retain the injectors in the rail during the engine assembly at the engine plant. They simply positioned and held the injectors in the rail. This allowed the rail and injectors to be easily handled and installed by the engine assembly line workers. How do I know this you ask???.....I toured the engine plant when the TPI and LT1 engines were being assembled and saw it first hand.
As for needing them when using injectors other than the originals, I personally would want to use the clips for the same reason. They would aid in the installation of the rail/injector assembly and would also "lock" the injectors in the correct position preventing them from pushing too far into the rail or into the manifold.

[QUOTE=63redcoupe]
You are correct in that the clips can help locate the injectors from top to bottom but in many cases there is little play for the injector to move up and down. In some cases the clip does not allow for proper alignment.
Many replacement injectors out there do not have slots located in the proper location in order to use the factory clips. In many instances people do not bother to use them.
The safety functionality is correct according to Delphi and we have no reason to disbelieve them. We will point out there there are many redundant fasteners in a vehicles fuel system to prevent lines from disconnecting and shearing during impact. Since an injector is basically floating the only anchor point it would have to maintain a seal on the pressure side are the clips.
FYI this past summer we did see a car with front end damage and the fuel rail had been lifted off one side of the manifold BUT the injectors were still hanging off of the fuel rail intact. If they had come off and fuel started pouring onto the hot exhaust manifold the car might had burst into flames.
Either way we are not going to turn this into a debate. Everybody can decide for themselves if retaining the clips is a priority to them.
The Delphi disc injectors have more than enough plastic around their inlets. This will allow additional groves to be cut if the ones provided by the factory do not align properly. There are many more unique applications than there are unique HP injectors.
