Z28 - 4053 mods when running the 140 cam
« on: September 21, 2019, 11:30:28 PM »
Other than jetting -
Does anyone have any advice on tweaking a 4053 to run better when the 140 cam is used?
Idle or high speed air bleeds or anything

Thanks in advance?

Use the SECONDARY Idle Speed Screw to set on-car idle speed after setting PRIMARY idle speed screw off the car to achieve optimum transfer slot exposure, and NOT CHANGE the Primary Idle Speed Screw once bench set.
