Sorry I didn't get back to you sooner. I could not find my Edelbrock Carb Owners Manual with all the dope in it.
So I called my mechanic buddy, and he looked in his book.
When I jet down my EDL-1404 for emissions, the set up is:
Chart position [11]
Jets -- .083
Rods -- 65 x 52
Once the State inspectors are satisfied, we retune to:
Chart position [6]
Jets -- .086
Rods -- 67 x 55
I run it that way all year, until September, when I go thru the whole process again.
If I registered the truck with a Vintage Year-Of-Manufacture [YOM] Plate from 1968 ARIZ, I could bypass annual emissions, but I'd have to change insurance companies, and since the Stepside is the daily driver for now I want full coverage.
