Howell EFI Just Announced Engine Transplant Applications

Howell EFI is a leader in wiring harnesses for many applications and conversions. They have recently expanded to not only cover more applications, but to cater to more projects through added parts and systems. The development of these systems is intended to bring more offerings to hot rodders, production project cars, and even off-roaders looking for more performance and fuel economy.

Howell has developed a complete throttle body and multiple-port fuel injection system using proven GM electronics, the Howell wiring harnesses, and 2/4-bbl TBI/TPI units. These are made for closed loop fuel and spark control, and also durability and fuel economy. Learn more about the new products from Howell EFI in their official press release below.

Official Release:

Regardless of the Engine Transplant, Howell Has You Covered — Wide Variety of Products for Amazing Number of Applications!

Currently Howell EFI offers wide-ranging GM-style EFI conversions for many applications and harness conversions for any GM V6 and V8 engine from 1985 to present. For anyone not doing a complete carbureted to fuel injection conversion, we also cover the transplant segment with 30+ years of vehicle applications.

As an adjunct to our wiring harnesses, we developed complete throttle body and multi-port fuel injection systems. We combine proven GM electronic components, Howell wiring harnesses, two and four-barrel TBI and TPI units. These systems offer GM closed-loop fuel and spark control, and typical GM durability and fuel economy. With extensive development on both big-block (454/502 CID) and small block (350/400 CID) engines, these systems are attractive updates for both hot rods, production carbureted vehicles, and off-road four wheel drive vehicles seeking both performance and fuel economy.

Whether you are looking to do a TBI, TPI, MPI, CPI, LTI (90’s & current LT1), LS, Vortec, or EcoTec3 EFI conversion or engine transplant, look no further than Howell.


At Howell EFI, we choose to sell only the best quality components, and all are covered by a money back guarantee. For additional information, visit or call 810-765-5100. Howell EFI is located at 6201 Industrial Way, Marine City, MI, 48039.
