Spec line question

[manny]

If in the spec line for a vehicle it states (1) holley/weber 5200 or fuel injection does the fuel injection mean that it has to be the stock setup that came on the vehicle or can it be some other type of injection? Under the throttle body spec line it says N/A.

Thank you in advance

Manny they clarified the Fuel Injection rules I think over last winter.

Here's the Level 2 rule. I think it's 9.1.5.E.2.b.4

Fuel Injection: All inducted air must pass through the
throttle body and be subject to control by the throttle
butterfly. The stock throttle body casting/housing must
be retained. The inside dimensions of the throttle body
casting/housing and all dimensions of the throttle butterfly
must remain stock. The throttle butterfly shaft must not
be relocated. The outside diameter of the portion of the
throttle butterfly shaft located in the throttle body bore
must be no smaller than stock. The contour of the interface
between the throttle butterfly shaft and the butterfly
must remain stock. The throttle butterfly and any throttle
butterfly to shaft screws/bolts can be attached to the
throttle butterfly shaft by any means including welding
or brazing. Holes or slots can be created in the throttle
butterfly for purposes of idle adjustment only. The number
of injectors must remain stock. The mounting position and
injection point must be stock. Electronic fuel injection may
be substituted for the stock type of fuel injection. In all
other respects the fuel injection system is unrestricted.

My reason for asking is that my car came with the speed density type of injection. Thank you for answering me.
