The Edelbrock 1/2" wood fiber laminate carburetor spacer (#8723) is a four‑hole spacer that enhances low‑rpm torque and throttle response while dampening reversion effects to the carb. Its wood fiber laminate construction provides heat insulation to reduce heat transfer to the carburetor. Use it to add insulation and modest plenum spacing without changing carb mounting geometry significantly.
