I noticed you're recommending a Edelbrock 1403 on a Performer EPS manifold further up in the post. Did your experience with EFI seem worth it?
My RQB-2978 came with a Edelbrock TM-1 (Torker) single plane manifold, which I've learned is intended for higher (3000+) RPM apps. I've never been real happy with low rpm drivability, So I'm replacing it with a Performer EPS and slapping the Carter 9625 back on. I am not assuming the 9625 is ok; if I can't tune it satisfactorily I was considering a new 1406 as there isn't even a choke on the 9625. But EFI is tempting too. Is it worth the extra effort and $$$? Is the 1403 a better budget choice? Not racing, 700r4, 3.08 gears, rarely sees >4000.
