Stock LS-1 is 75mm. The MAF is also 75mm. STock LS-2’s are 90mm.
Are LS throttle bodies interchangeable?
Other than a few GM part number updates, the equipment remained the same and electronic throttle equipment can be interchanged. The LS1 and LS6 engines received the same equipment. Everything changed (throttle body, pedal assembly, and TAC) when the LS2 engine was introduced in 2005.
What size throttle body should I use?
The general rule is: the bigger the size, the higher the RPM needed for a kick of power. If your new throttle body is too big your vehicle will feel tired at lower RPMs, while really taking off powerfully at higher RPMs (when the engine’s demand of air flow matches up with the the internal bore’a bigger size).
What size is the LS2 throttle body?
90mm
All LS2 manifolds have a 90mm throttle body opening and are set up for electronic throttle controls.
What year LS has cable throttle?
1998
LS1 Throttle Bodies & Adapters The very first LS throttle body was an electronic throttle, also known as drive-by-wire. The electronic throttle was released before the cable throttle, but in 1998, the LS1 engine for both Camaros and Firebirds moved to cable throttle.
What size throttle body does a LS7 have?
19420707 – LS3/LS7 90mm DBW Throttle Body.
Is drive by wire better?
The signals from the Throttle Position Sensor and the input from the potentiometer connected to the accelerator pedal, helps the ECU to perform the ‘throttling’ with greater accuracy. Drive-By-Wire eliminates the need for any mechanical linkages and hence aid in weight savings.
Is a LS7 a big block?
in. To clarify, the LS7 engine code can also refer to a 454 cubic-inch Big Block V8 with a 460 horsepower, which was offered in iconic GM muscle cars throughout the 1970s, including the Chevrolet Caprice, Chevelle, Corvette, El Camino, Monte Carlo, and GMC Sprint.

What size throttle body should I run?
More on this in a minute. Going up in displacement to the 103-inch engines and the 110s, a 55mm to a 58mm throttle body can be a good pick. If that engine also has those top-of-the-line/high-flowing heads, a 103 can even benefit from a throttle body all the way up to that 58mm size.
Can a throttle body be too big?
Yes. A large throttle body will provide you with a handful of benefits with one of the most notable being a boost to overall horsepower. It will also improve acceleration performance and so much more. Within this guide, you’re going to learn more about the throttle body and the benefits that can be obtained by making the upgrade to a bigger one.
