Holley 650 DP on 360 - secondaries issue

[Swingerdude]

Hi there.

I have just installed a Holley 650 DP on a 360 mopar with an Eddy RPM intake. 727, 8 3/4.

Before that, i was running an Eddy 600 vac.sec. (which is now sold)

When i put the pedal to the floor, the carb's primaries are open, but the secondaries are just about to. When pulling the throttle manually with my hand, it opens fully. Looks like the cable can't move far enough to pull the throttle all the way back.

It's a stock cable and kickdown linkage.
I've installed the chrysler adapter on the carb.

Any ideas and help is very welcome...

I had the same problem with mine and it required the bracket that holds the throttle cable to be modified up and forward so I could get full throttle. This also helped by having the kickdown linkage in the right place as well after adjusting it.

YOU have to play with this issue and keep adjusting things until you get what your looking for.
