Holley Six Pack Diff Between #4374 and #4375 Centers? - 09/23/12 02:33 AM
I know that the #4374 was for N95 CA emissions, but what did that add or take away from the #4375? Thanks in advance for any input!

4375 is for a manual application, the 4374 is Auto, and unlike the 340 centers (4791/92) the 440 centers have the same CFM rating

R4374 = '70 440 4-spd N95
R4375 = '70 440 4-spd
R4376 = '70 440 auto
