Here's how the whole Inglese system looks installed on the engine and ready to go. For this 572, we went with a sheetmetal/custom-look intake since the Chevelle it's destined for will have a serious restomod theme.
EZ Flavor
If you grew up in the '60s, seeing a car with Weber carbs-those eight stacks gulping in air to feed some sort of octane-burning monster-would make you take notice. Amongst a sea of four-barrel carburetors, a car sporting multiple Webers always stood out with its own coolness factor. Flash forward, and fuel injection has spread faster than kudzu through the hobby. More and more people are embracing electronic fuel injection and all its benefits, but yearn for a more classic-looking EFI system to give their vintage cars a period correct look.
Seeing the need for something different, Inglese, the induction gurus who know how to deliver a fuel/air mixture in style, came up with an EFI system with the classic look of an eight-pipe Weber carb setup. The new Inglese system can support up to 1,000 hp engines, and thanks to EFI, can handle a broad range of camshafts, allowing for a wide variety of applications. The Inglese system uses sister company FAST's XFI or EZ EFI electronics to manage everything, along with an optional FAST Dual-Sync distributor to light it off. Other features of the Inglese system are FAST Precision Flow fuel injectors (based off the LS7 injector design), cast-aluminum throttle bodies, low profile CNC-billet fuel rails, and a number of different intake manifold combinations depending on the look you want.
The Inglese EFI system uses...
The Inglese EFI system uses LS7-style fuel injectors (offered by FAST in various fuel lb-hr ratings) to provide maximum performance. For our application, we went with 50 psi squirters to start and for the final cam, went up to 85 psi units. These injectors are available in two different height configurations, and can easily be dropped into any LS engine for increased fuel flow performance.
We were working with Inglese's parent company, Comp Cams, to get some more power out of a GM Performance Parts 620hp 572 crate engine. While on the Comp dyno, we baselined the engine stock with the Inglese system using FAST's new self-tuning EZ EFI control system. The EZ EFI is a fantastic set up, compatible with any engine running an intake manifold with a Holley 4150-style carb flange, or other fuel injection systems, and supports up to 600 ponies.
The great thing is no laptop is needed to get the system running properly once installed. Just turn the key, let the engine warm up, then drive it around for a few minutes. The EZ EFI's self-learning system adjusts the fuel maps/curves, air/fuel ratio, and other factors to achieve an optimal setting. If you want to do some tweaking, the included control box (mountable anywhere in the car) lets you tweak the system for your individual tastes, even if you're not a computer expert.
Follow along as we tested out both the EZ EFI and Inglese systems on the Comp Cams dyno, and even threw a few different cams at the engine to see what it would do.
 The fuel rails and injectors...  The fuel rails and injectors on the Inglese EFI system are hidden down between the stacks so that at first glance, no one will notice this is an EFI system. Since the EZ EFI control harness uses standard GM injector plugs, no adapter is required to work with the FAST LS7-style injectors. The EZ EFI harness is also fairly idiot proof so it's very hard to incorrectly hook up the fuel injectors to the control harness. |  Here's a look at everything...  Here's a look at everything plugged in before the rails are dropped onto the injectors and bolted to the manifold. |  On a dyno or in an engine...  On a dyno or in an engine compartment, plugging in the EZ EFI system is quick and easy. You can custom-route the wiring harness to however you want your engine compartment to look, and every plug is marked so you know exactly where it goes. |
