Street Rod LS376 EFI Stacks Engine
The LS3 is already electronically fuel injected. Why add an EFI stack system? Ask yourself a question, "Why go with 21in billet wheels and tires when you car already at 21in wheels and tires from the factory?" The answer is the same for both. It just looks cooler. A dyno rating of 567 horsepower is a pretty good reason too.
