Best Answer:Hi John, I'm glad to assist you. This is a complete kit for anybody planning to convert from a carburetor to Atomic EFI. You get the throttle Body, Power module (with Wide Band O2 sensor), Handheld Controller, and the Standard Fuel Kit for up to 525hp (at the crank).

What else does a guy need to put this product on a 300 6 cly ?John G.May 20, 2021
Best Answer:Hi John, I'm glad to help you out. Based on the manufacturer's website, this part will not fit the Chrysler 300 6 Cyl. This is for custom-built engines with 4-barrel square bore type. If you have an aftermarket manifold or a 4-barrel adaptor, then this will fit. I suggest calling the manufacturer Holley at 1-866-464-6553. The kit comes with everything you need to install it. Though, this is not an entry-level install. If you're handy and have basic skills, it'll be fine. I hope this helps. You can click on the link below to get back to the product page. Have a nice day. <a href="https://www.carparts.com/fuel-injection-kit/msd/m462900?can=CPGG4850" target="_blank">https://www.carparts.com/fuel-injection-kit/msd/m462900?can=CPGG4850</a>
