Anybody rejetted their 1406 Edel carb ? What did you find ???

[Green Machine]

Putting a 1406 on our latest project. This is my first edelbrock, used many holleys before. Most carbs are a little rich so I am assuming some tuning will be needed for best mpg/performance.

What have you done or found out about your 1406 ? Hve you needed to change front or rear jets ? Change rods or springs ???

Just wondering if there are any general tendencies of these carbs to be off in one certain area that usually need changed ?

I know all engine setups are diffferent and I will have to tune to my specific setup. But if I know they are like "always lean in the back" I'll just have a better place to start. Please list any jet sizes or rod numbers, spring color, etc. if you can. Thanks.
