Small-Block Performance Upgrades From Holley

If you have a traditional small block that you want to modernize, we have found the parts for you. Check out Holley Performance Products’ latest releases of Flowtech headers, Holley Intake, and Terminator X EFI.

Spent Fumes

To start your mouse modernization, Flowtech just launched its new stainless-steel turbo headers. These can be mounted in a variety of positions, making your next turbo install a breeze. Flowtech’s new Turbo headers are available with 1 3/4- and 1 7/8-inch mandrel-bent tube diameters and 3-inch collectors that contain merge spears for increased exhaust velocity. The Flowtech SBC Turbo headers are the ideal design for creating a compact package within your engine bay. They also allow a variety of configurations (up/forward, down/forward, or down/back).

Flowtech’s turbo headers are available in 1 3/4- and 1 7/8-inch mandrel-bent tube diameters with 3-inch collectors. Perfect for you heavy-breathing small block.

The headers use a 1/2-inch-thick flange for a leak-free seal, and 3-inch V-band flanges for a superior seal and even pressure at the collector flange. The headers are available in ceramic-coated mild-steel, natural 304 stainless-steel, or polished 304 stainless-steel.

New Fuel

Holley’s new single-plane EFI intake manifold for Vortec heads is designed to provide a broad RPM powerband for high-performance street/strip engines spinning to a maximum engine speed of 7,500rpm. The manifold is designed to work with 4150-style throttle-body EFI systems like Holley’s P/Ns 112-587 and 112-588. These intake manifolds are designed to accept most stock hardware and accessory brackets and offer performance features like an updated plenum divider area, a 1-inch-shorter overall height than most single-plane manifolds, and a choice of two distributor clamp locations.

The black fuel rails and rail bracket are included with the manifold for any easy installation with the injectors you choose for your combination. Available in multiple configurations to accommodate factory iron, Vortec, and most 23-degree configuration aftermarket cylinder heads. Holley’s new 4150-style fuel injection intakes are a perfect complement to its new Terminator X Universal MPFI kits.

Time For Termination

If you need to control your modernized engine, do so with Holley’s Universal Terminator X. Don’t settle for a cobbled-up factory ECU with a cumbersome tuning interface. Give yourself complete control of your engine with self-learning fuel strategies and the proven, race-winning technology of Holley EFI at a budget-friendly price. Terminator X comes loaded with base maps for common V8 engine combinations to get you out of the garage and on the road or track — fast. The 3 1/2-inch touch screen contains an easy to use calibration wizard as well as tuning and gauge display functions.
