Howell Engine Developments

Howell Engine Developments' goal is to reduce the difficulty in adapting late model GM engines or fuel injection systems in older pre-computer vehicles of all types.

Howell Engine Developments, Inc. was formed in 1988 by Bill and Matt Howell to support the growing trend towards the use of electronic fuel injection in the Hot Rod/Street Rod and Four Wheel Drive Industries.

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 performance and fuel economy.

We choose to sell only the best quality components, and all are covered by a money back guarantee. We reserve the right to charge a restocking fee on all new parts returned. Our normal parts guarantee is replacement, if they fail within 90 days of service. On used or rebuilt parts such as ECMs, distributors, etc., our guarantee is for 6 months of service.
