Some of the Holley Commander 950 Throttle Body Fuel Injection Systems are two-barrel throttle bodies.
Two-Barrel Throttle Bodies:
Holley 950-19S 400 cfm / 100 to 250 hp
Holley 950-20S 670 cfm / 125 to 275 hp
For more than about 220 hp you may want to consider the 4 barrel throttle bodies.
Four-Barrel Throttle bodies:
Holley 950-23S 650 cfm / 150 to 325 hp
Holley 950-22S 700 cfm / 250 to 400 hp
