Holley 670 CFM 2-bbl GM Truck TBI

Bolt on Power...
Instantly with this excellent, direct replacement for your O.E. GM TBI unit. 2.0'' throttle bores provide 42% more area than stock for flow that is unmatched! Fully compatible with all O.E. plug-ins for a quick, hassle-free installation.

Holley SB-Chevy Pro-Jection Manifolds

Product images may differ from actual product appearance.
RPM Range: Idle-6000
Designed for use with 2-bbl Pro-Jection throttle bodies. Utilizes a high rise/dual plane design, Idle-6000rpm power band, features exhaust heat cross-over, EGR provision and late model alternator and A/C mounts.

While the Holley manifold does have 2 inch throttle bores to match their TBI, Edelbrock a sure me that using their Performer manifold with 1-11/16 throttle bores will not give up any power to the Holley, and using the require adapter plate will smooth out the idle.

The other main reason I am high lighting the edelbrock manifold is that it is basically the same as the stock unit. Holley relocates the EGR, and the TBI is relocated just enough to mess with the transmission cable, which is important to have correctly adjusted.

Holley Commander 950 Throttle Body Systems

Product images may differ from actual product appearance.
Complete Do-It-Yourself Fuel Injection
Holley's top-of-the-line Commander 950 Throttle Body Systems high performance system puts the world's newest technology at your fingertips. Commander 950 is the ultimate in ECU technology. Designed to retro-fit carbureted, non-computerized V8 engines, these digital systems provide smooth, precise performance under all kinds of operating conditions. Sizes to accommodate HP ranges from 225 to 500. The Commander 950 Throttle Body Systems has been revamped and upgraded with all new electronics and injectors, and also some significant throttle body design improvements. Electronic capability has been significantly upgraded with the inclusion of the Commander 950 ECU. Totally programmable, this digital ECU is defining the state-of-the-art in its sophistication and capability to control a myriad of engine functions relating to the management of an emgine's fuel and ignition functions. Throttle bodies have been redesigned to accommodate a new injector pod and wiring harness. As a result, a qualitive improvement has been realized in idle control, power application and overall driving responsivness. Also, secondary throttle linkage is now progressive in operation, as opposed to the 1:1 ratio of the former design. This linkage reconfiguration has contributed to better overall driving experience especially in off-idle and during part-throttle cruise situations.

Accel Performance Fuel Injectors

Accel Performance Fuel Injectors
Featuring a high-impedance design to function properly with the specified vehicle's ECUs, Accel's Performance Fuel injectors are all-new units, not remanufactured from used cores. They utilize a precision-ground Bosch-style pintle design, which produces a wide-angle conical sprat pattern of 150 micron diameter droplets, providing an ultra-fine fuel atomization and maximum emulsification for improved burn efficiency. This pintle design also produces a more accurate and consistently more repeatable fuel flow control than either the ball valve seat/deflector plate or disk injector designs. Accel Performance Fuel Injectors are 100% flow tested, balanced and marched to within +/- 1.5% of their normal pound/flow rating.

Accel Performance fuel injectors also feature an anti-plugging vapor cap that virtually eliminates carbon build-up. Accel's low-mass internal needle valve and high-pressure spring assembly ensure faster response time and greater dramatic response range. These injectors also feature their noted flow rating permanently laser etched into the Accel-yellow molded top for the unmatched combination of great looks and instant recognition. They come complete and ready for installation with precision-molded O-rings and fine mesh fuel strainers.
