Re: Edl 1409
I've got a 1409 on my truck with electric choke. I just get my manifold vacuum off the manifold. It is jetted richer than the 1406. It sure runs a lot better than my old out of the box 1406's. I am going to jet my 1406's just like my 1409. I don't think the lack of vacuum ports on the 1409 is that big a deal on an old Chev.
I can't even get a Quadrajet to outperform my 1409 yet. I'm still working on it because the Quadrajet has a much better automatic choke system.
