I have a '70 455 with a fairly big cam (Kenne Bell Maxi 3: 232 intake, 260 exhaust @ .050"), non-stage heads, headers and Performer manifold and Q-jet. I drive the car only on the street and have to spend at least two minutes at about 2000 rpm otherwise it'll die when I let go of the throttle. I'm guessing the thermostatic choke on the Q-jet isn't working too good. I like the idea of the spreadbore carbs for driveability and part throttle performance and want to stay with that but Q-jet specialists seem like they're getting hard to find, so I've been looking at Edelbrock carbs. Does anyone have any experience with these? Or should I just try and find a Q-jet specialist and have mine rebuilt? I'm in the Chicago area, in case anyone knows of someone who can rebuild my carb.
Thanks in advance.
