Got an intake manifold with a traditional 4150-style carburetor mounting flange?

Then the Holley folks have made it really easy for you to bolt-on one of their Terminator X Stealth EFI conversion systems.

Backed by Holley’s highly-capable Terminator engine management system, these electronic fuel injection kits are able to handle up to 650 (NA) or 1,250 (forced induction) horsepower.

That makes them good fit for a lot of race applications. But since most of the Stealth kit’s wiring gets tucked out of view behind other components, this package also looks nice and tidy on a classic restomod engine too.
