Overall Assessment

Customers appreciate the product for its high-quality and good fit. Its classic, retro aesthetic appeals to users, especially when paired with the Holley intake, throttle body, and air cleaner. It enhances builds, including for a 32 roadster and a 5.3 turbo build for an '84 Caprice. Users recommend it for retaining port EFI while also enhancing the look of their builds. The product is valued for its practicality, quality material, and reliable performance.

As this is being installed on a 32 roadster: the mix of a classic retro look plus the ability to retain port EFI were important to this build. The combination of the Holley intake, the throttle body and air cleaner together made this possible. As I am a stickler for hardware fastener appearance/overall match, most items I purchase always need something to match the theme...

What would be the other part number I need for the spark controller as well as to complete the multiport fuel injection? I am curious as to which throttle body, injectors and fuel rails i would need to complete the kit.
