Howell EFI Announces Mopar TBI Kit Offerings

Howell EFI has always been very well respected for their many Jeep TBI kits for the off-road market, as well as their many kits for the 304, 360 and 401. Now available are Mopar TBI kits from 273 to 440 V8 engines. In fact, for anyone interested in converting a V6 or V8 engine from carburetor to throttle body fuel injection with an ignition other than points, Howell can create a throttle body kit for any configuration.  If you don’t see the part # you are looking for, give us a call.

The kit features a remanufactured GM throttle body appropriate for your engine size, and operates engines with or without ECM controlled ignition. It contains all sensors, components, wiring harnesses, ECM and fuel pump to install fuel injection on your engine. Also includes custom calibration PROM, and an ECM that installs under the dash. The fuel pump installs in the main fuel line, and bypass fuel is returned to the tank. Harnesses include a diagnostic connector, and diagnostic is similar to 1986-92 GM pickup. The kits have proven to be especially popular for older street-driven, or 4 wheel drive vehicles, and greatly increase drive-ability, fuel mileage, and cold starting.

Look to Howell EFI to make your conversion happen with ease. Link to video here.
