ACES Fuel Injection Killshot Throttle Body/EFI System Top End Kit for Small/Big-Block Chevy

From black or polished to a gold finish, this throttle body and EFI system top end kit gets your ride looking and driving like a king. With this ACES Fuel Injection kit, you can connect unbeatable power to almost any 4150-flange, four-barrel manifold with a Small or Big Block Chevy engine. This is thanks to the throttle body, configured like a four-barrel carburetor and integrated with four 100 lb/hr fuel injectors. While TPS and MAP sensors are incorporated within it, it’s carefully designed separate from the ECU. In doing so, you won’t have to deal with unwanted engine heat and vibrations.

Features and Benefits:
- Fits most 4150-flange, 4-barrel intake manifolds

- TPS & MAP sensors built into throttle body
- Blackjack Pro distributor with CNC-machined, cast aluminum body
- Sealed ball bearing on top, sintered steel bushing on bottom
- Maintains stability up to 10,000 RPM
- Coil upgrade for efficient heat dissipation
- High-output magnet creates 70% more spark energy than stock
- Significantly hotter, larger spark leads to more HP & TQ
- Square shape on coil allows firewall/fender mounting
- Startup wizard & self-learning ECU simplify installation
- Consistently & quickly manages in/output, signals, voltage, & RPM
- Automotive-grade, die-cast aluminum ECU housing
- Configurable for boost & nitrous applications via laptop

Ideal for 200 to 600 horsepower applications, the kit also comes with a Blackjack Pro distributor. Its body is expertly machined from cast aluminum with a sealed ball bearing on top and sintered steel bushing at the bottom. Together, they help it sustain stability up to 10,000 RPM. Drivers also get a coil upgrade that’s not just stellar at heat dissipation but offers 70% more spark energy than stock-style applications. A high-output magnet helps achieve this, spawning 50,000 volts for remarkably hotter and larger sparks. Perfect for a more complete combustion, it builds up horsepower, torque, and acceleration without sweat.

Vehicle Fitment:
- 1960-1987 Chevy C10
- 1964.5-1985 Ford Mustang
- 1966-1977 Ford Bronco
- 1948-1979 Ford F-100
*For models with a Small or Big-Block Chevy engine ONLY

Installing the kit is easy since the coil has a square that practically encourages firewall and fender mounting. Tuning is straightforward too because the supplied handheld tuner opens a wizard upon startup. After asking a handful of questions, the ECU then takes it upon itself to build a tune custom to your vehicle based on 30-60 minutes of idling and drive time. You can even calibrate it for boost, nitrous, and further dyno tuning using only a laptop.

Tech Tip: The self-learning function works best for stock to mildly modified applications. For more aggressive applications and even some stock/mild applications, ACES Fuel Injection offers free tuning software on their website.
