I run an EFI Spyder intake on my 377 stroker. This intake is a single plane Victor Jr. carburator manifold that has been modified by having fuel injector bosses welded into it. Then they add a custom fabricated 90 degree upper connector to the throttle body. However, whether you would want to run this intake or not would heavily depend on your application, the power band you need or are looking for, and other factors. If you don't have a more serious combination, where you are going to run higher RPM's, you may not want this intake. It will have far less low end torque, and will have a high RPM band. The power in my car doesn't really come in until over 3500 RPM and this intake will reach it's full potential until much higher (7000 to 8000 RPM). If you stick this thing on a intermediate 5.0 combination meant for the street (2500 to 6000 RPM band) it will probably kill it because you will probably have poor low end torque. The same thing happens trying to use something like a Saleen Intake (truck lower) on a 5.0L street combo.
However, if you have a serious engine that makes a ton of power, killing the low end some can be beneficial though. At the track it makes it easier to hook up and on the street there's still enough low end to make it crazy any ways.
Hope this helps...
