Edelbrock has gotten real proud of their stuff lately, sad because it's generally decent stuff. Summit has them, $345 for a new 1406, $312 for a factory refurbished one. You can find a third party reman 1406 on Amazon for much less.

They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.
