It was a brand new carburetor, model 1406 (street economy). They did do some rejetting I know after talking to people at Edelbrock. I live by Denver and the Edelbrock guys said that this particular carburetor shouldn't need to have anything done to it. I also know they are at least opening some because when I got it back they weren't opening at all due to the fact they were hitting a spacer plate they added to try to minimize the heat issue from the engine causing the car to hesitate bad (they added a elec. Fuel pump that cleared that up). So, after an adjustment in the plate, the secondary does open up. It feels like it isn't getting enough air would be the best description I can think of to give.

Have you checked to see if they are opening All the way or at all, on the Edelbrock? Have you tried rejeting the carb?

I also Have a 4 speed. All of this is in a 1964 Dodge Polara 500 convertible. I Replaced the Carter with the Edelbrock last fall and don't even remotely Like the performance compared to the Carter. With the Carter 4 bbl opened Up, the car really jumped. The place that put the carb on is your average Auto repair shop that probably felt that the carb was on and working. No Disrespect to the job they did in any way. I want more performance out of The car and didn't say it in a way that was totally understood. I don't want To race the car, but when I have that urge to spend some of that expensive Gas quickly, I want to fell like I'm spending it fast!! BTW, thanks for all the replies to my question.

Stock manifolds too. Ran Like a clock. Sweetest motor I've ever had. Had it in three different cars. ---- Please address private mail -- mail of interest to only one person -- directly to that person.
