What should I set the high and low idle speeds to on a 1970 383 with an Edelbrock 1406 and an automatic transmission? This is the 4 barrel version of the 383. The manual has several idle speed specs, depending on what carb was on the car (i.e. 700/1700 and 750/1800). That made me think it was wholly dependent on the carb, but the Edelbrock 1406 manual does not have idle speed specs, which now leads me to think it depends on numerous factors.
This car sat for years and I am just trying to...
Idle speed?
