Here is how to hide injectors and fly-by-wire, using a Holley Terminator throttle body as an air-only apparatus.
We use a Holley dual-plane manifold for correct appearance, position injector bungs so we can lay the rails as close to the valve covers as possible.
Shot-peen after welding/grinding/smoothing.
Use ACME fly-by-wire carburetor adapter kit, which accepts a modified 90MM GM throttle body motor.
Modify the Holley throttle body to use Gen IV Map sensor and IAT, blocking TBI ports and idle air port.
Build aluminum valve covers to hide the rails and coil packs: Those valve covers started out as Edelbrock polished cast aluminum coil covers, and after a lot of time in the mill and flat filing, welding, grinding, and flat filing some more, we ended up successfully hiding the injectors and rails.
Utilize factory GM PCM or Holley Terminator ECU. This one was GM PCM.
We always correctly plumb PCV and make sure all the little details work like the factory intended. Though an automatic, it made just over 400 horsepower at the tire, about 30 more than a factory LS3 Corvette through a six speed.
We raptor lined the valve covers and coil covers for sound deadening. Holley intake and exhaust manifold, ground and shotpeened. Keco coatings in Statesville mixed up a gray ceramic coating we thought looked the part for the exhaust manifolds.
We built a 3” stainless exhaust through Borla mufflers with our tuned X-pipe. It sounded great on acceleration and decel. Contact us for pricing.
