Holley Secondary Linkage 20-122 - 05/09/18 06:19 PM
I've been messing around with my Holley 850 DP. I can't seem to get the secondary throttle blades to open all the way. They are close but not quite straight up and down like the primary throttle blades.
Car is a 1967 Satellite originally came with a 318 with a 440 now with RPM intake, AR tall throttle bracket, 1/2" spacer and Holley 850 DP. I've tried the original 318 throttle cable and a Slant 6 throttle cable PN ATP Y155 but still had the same problem.
Has anyone here messed around with using the Holley secondary linkage PN 20-122 to fix this problem?

I've also read about people taking out the original linkage rod and heating it up and bending it to solve the problem.
Thanks in advance for any ideas.
