Holley 4160 600CFM - 472 Cadillac

Post by MD3 »

Have a Holley 4160 600CFM on my 472. My secondary is opening too soon. Can anyone recommend what spring "color" from Holley I should install to slow the opening of my secondary

Thanks

Doug

is this a direct drive or gear?
I still think I-10 is the Mason Dixon line.
