What Throttle Body Should I Run on an LS-Swapped Chevy C10?
Throttle body choice is about control, compatibility, and response — not just size.
Short answer: choose a throttle body that matches your intake manifold and your throttle strategy (cable or drive-by-wire). Bigger isn’t always better on a street truck — the best throttle body is the one that delivers smooth, predictable response and works cleanly with your ECU and wiring.
“A throttle body should make the truck easier to drive — not harder to tune.”
Start With Compatibility
- Intake manifold flange: confirm bolt pattern and opening size
- Cable vs DBW: throttle body must match your strategy
- ECU support: especially important for DBW control
Why “Too Big” Can Feel Worse
Oversized throttle bodies can make low-speed response touchy and tuning less forgiving. Street trucks benefit from predictable airflow and usable midrange response.

Make Throttle Response Feel OEM-Level
Smooth response comes from matching parts and planning wiring and airflow as one system.
