1971 Match Race ~ 'Duster 340' vs. 'Boss 351 Mustang'

EL5,

Regarding the 71' Boss 351 #4300-D Carburetor

Ford does list it at 715 CFM.

But Gapp & Roush had it at 750 CFM with the 1.565" Primary ~ 1.690" Secondary

There recommendation was to replace the Boss 351 Aluminum Dual-Plane Intake
with an Edelbrock #F351 Unit, and switch to a Holley #9510 780 CFM Carburetor.

Worth 3/10's and 1.5 MPH in the 1/4 Mile.
