Truck avenger "spring and perch kit"

[daves77]

I am looking over the instructions for the Holley Truck Avenger 670 and it calls for Ford apps to run with Part Number 20-91, spring and perch kit, for Ford automatic transmissions. I do not have this kit and the carb. I am taking off the bronco is a Carter 600 cfm. I am not one for disregarding instructions, but just wondering if this is the only additional parts I need?

FYI-I will also install a 1" riser.

Honestly the best thing you cn do is call Holley or email their tech department and tell them what you are trying to do. They will give you part numbers to everything you need. If you want the instructions they may be online or I can fax you copies of mine with all of my greasy finger prints on them.

I had to get a kickdown kit and a kit for the throttle linkage. I also run a 351W but I did a new intake at the same time too. They helped all the way.

PM me if you need anything.
