What years did Chevy use throttle body injection?
The short answer is that Chevy officially used throttle body injection from 1987 to 1995. There were other more primitive forms of throttle body injection found about 5 years earlier, called cross-fire injection that was introduced and used only on the 350 that powered the 1982 and 1984 Corvettes.
What controls the injectors on a TBI?
The vehicle's fuel pump moves fuel from the gas tank to the throttle body assembly. Then a computer, often referred to as the powertrain control module (PCM), activates the TBI injectors. The injectors spray fuel into the throttle body bore, right above the throttle plates.
Can you put Vortec heads on a TBI 350?
The heads will bolt to the block fine but you will need a specific intake manifold. Either the gm TBI/vortec intake or a vortec intake for carbs and use an adapter for the tbi.
Will TBI heads fit older block?
Regarding physical interchange: Yes, the heads in this group physically bolt on to your existing short-block but require a unique intake manifold and corresponding intake-gasket set because the center two intake-manifold-to-cylinder-head attaching bolts are drilled at a different angle than traditional small-block ...

Is a throttle body the same as fuel injection?
Here's what you need to understand: While a carburetor moves both fuel and air (and must be sized according to engine size and horsepower), an EFI throttle body moves only air, essentially serving as an air door. Fuel delivery is controlled by the electronically operated injectors.
What are the advantages of throttle body injection?
The main advantages of using TBI to supply fuel to the engine are: Simple and quick start of the car (compared to carburetor versions) Reducing fuel consumption by increasing engine efficiency both when the machine is moving and when starting.
Is TBI a carburetor?
TBI, throttle-body injection, also known as the carburetor with a brain. TBI systems use a dual-plane aluminum intake manifold and a throttle body with two injectors that deliver fuel to the engine.
What are the 2 types of throttle body?
The throttle is either open or closed (although there is always a small hole or other bypass to allow a small amount of air to flow through so the engine can idle when the throttle is closed), or some intermediate position.
What is a DUI distributor?
DUI is the brand name of a large cap (GM HEI style) distributor manufactured by performance distributors (performancedistributors.com). These distributors are a more expensive option and well worth the expense for both looks and performance. This option does not increase the performance over the standard ECM controlled distributor, it is just a simpler distributor and has a very appealing look.This distributor option is non-refundable. There is potentially a 6-8 week lead time for this option
Do TBI systems require an electronic distributor?
These systems are intended for stock engines only. Some engine selections start at a higher cost due to a larger throttle body and larger injectors. All TBI systems require an electronic distributor. An explanation of your selection will appear below this input when you select an option.
What is a TBI?
The GM TBI is a speed-density system, which assumes the engine ingests a given amount of air at wide-open throttle (WOT). Mass airflow systems measure the air entering the engine, but speed density systems like those used on these TBI engines do not.
How much horsepower can a TBI make?
Stock small-block throttle bodies only flow around 500 cfm (compared with a stock Q-jet that flows 750 cfm). It's possible to make around 275 hp with a stock TBI unit, so rather than go nuts on a heavily modified TBI, I'd suggest you start by making sure the existing TBI unit and injectors are in good shape. The actual throttle plate diameters for the 4.3/5.0/5.7L TBI units are all the same at 111/16 inches (big-block TBIs are 2 inches). The difference is the injector flow rates. The 5.0L injectors flow 40 to 45 lb/hr, the 5.7 ones are 50 to 55 lb/hr, and the big-block injectors flow around 75 lb/hr. We would suggest sticking with the stock 5.7L injectors to begin your testing.
How much fuel pressure is needed for a TBI injector?
The big variable is fuel pressure. These late-'80s and early-'90s TBI injectors are intended to run at between 11 and 13 psi, although it's typical to see the pressure down around 10 psi. Generally, a 1-psi change in fuel pressure—from 11 to 12 psi, for example—can be worth roughly an additional 4 percent fuel flow. That doesn't sound like much, but going from 50 to 52 lb/hr can be enough fuel to make another 8 to 10 hp.
