It depends on where you are on the sphere, but here is how it generally works.

Orders are fulfilled first-come, first-served within 1-2 business days. (Orders placed after 4:00 PM EST are typically fulfilled the following business day).

Once your order is packed up and on its way, our shipping partners take over. How quickly it arrives depends on the delivery option you chose at checkout.

Note: You can always pick up your order at our Chattanooga location, but make sure you call us at least 1 hour in advance so we can make sure it's ready for you in time :)

You bet! Just keep in mind that for international orders, we do not currently collect duties and taxes at checkout. You would need to pay these fees before our shipping partner delivers it to you, and they would reach out to you before delivery with a secure payment link.

Don't want to worry about duties and import taxes? Reach out to us to see if we have a reseller in your area, and we can help hand over the transaction to them for an even faster purchase!

Many of our systems work with a wide variety of engine combinations. We have TBI-style systems that fit 2300 and 4150-style flanges respectively and are designed for classic engines (engines which use distributors); Port Injection (MPEFI) systems that are designed for classic small blocks and some big blocks (Chevy/Ford); and LS systems for LS1, LS2, LS3, LS6, L92, LR4, and many other LS style engines. We also offer standalone engine management systems for LT and Hemi platforms.

For classic engines, our TBI (throttle body injection) and MPEFI (multi-port EFI) systems include:

• Deuces Wild: A 2 bbl TBI system with a 2300 style flange supporting up to 350 HP
• Killshot Classic: A 4-bbl TBI system with a 4150 style flange designed for use with stock ignition and not capable of timing control. Supports up to 450 HP
• Killshot: A 4-bbl TBI system with a 4150 style flange designed for use with “locked out” ignition and capable of running timing control. Supports up to 650 HP
• Royal Flush: A 4-bbl TBI system with integrated CDI (capacitor discharge ignition) and a 4150 style flange designed for use with “locked out” ignition and capable of running timing control. Supports up to 650 HP
• Wild Card: A MPEFI sequential EFI system that supports classic 8-cylinder engines and uses a 7+1 Hall Effects distributor.

The Joker: A MPEFI sequential EFI system with integrated CDI that supports classic 8-cylinder engines and uses a 7+1 Hall Effects distributor.

Our technicians recommend running any EFI-compatible fuel system that is regulated at a minimum of 42-60 PSI and runs at 255 LPH.

For Carburetor/stock EFI to EFI Conversions on classic engines:

• EFI System is compatible with your application
• Fuel Delivery System capable of supporting a minimum of 42 PSI
• A distributor that is or can be locked out, and a separate ignition coil (if you want to run timing control). 
• For stock applications under 450 HP, you can just use your stock ignition if paired with the Killshot Classic. 
• Note that our MPEFI systems require a 7+1 Hall effect distributor in work.

For Engine swaps using *LS, *LT, or *Hemi engine platforms.

• Jackpot EFI system (TBI and MPEFI options available)
• The system is compatible with stock coils
• Fuel Delivery System capable of supporting a minimum of 42 PSI

*Does not support DOD or VVT.

Our systems are manufactured in China and designed & supported in the USA.

We offer both 2 and 4-bbl TBI systems. Our 2-barrel system can be found here, and it supports up to 350 HP using a 2300-style flange. We currently offer several 4-bbl TBI systems whose features vary depending on the application, but they all support up to 650 HP using a 4150-style flange. Check out our most popular one here!

For classic 8-cylinder engines, we offer two systems. The Wild Card and The Joker. Both of these systems are the same except that The Joker has built-in CDI in the ECU.

For LS engines, we offer the Jackpot system.
