Hey guys, I am looking for info on what metering rods and metering jets to replace on my Edelbrock 1406, running pretty rough after warmed up until the RPM'S increase to clean out the ports. Running at 5,280 altitude here in Denver & the car came from Chicago. So in the past high altitude would mean to change the Metering Rods & Metering Jets. Q. is for this carb and high altitude what would you guys recommend? Thanks for the info here.
