Pinto Car Club of America

 put a small hyd cam in the old girl 454 lift had 50 idle jets in to start , both sides if I go up in size do I change both sides thanks for any help getting ready for 2011 woodie

You can put it in just on the primary side if you want. The primary side is the one that is actually working when the car is running at idle. The secondary idle jet comes into play when the secondary butterfly starts to open.
