I don’t have experience with the 500 cfm but I do have 2 600 cfm. Manual and electric. The electric choke versions tend to be more of the emission and fuel economy style and at least with my 600 jetted leaner. I would have preferred the 500 but I’m cheap and good deals came up on both 600’s. Although the 600 will work, stick with the 500. It’ll run better.

Getting the kit as TKO suggested is a good idea but you could try the carb as is and order the kit later. If you get the electric choke version, do not connect it to the coil. If you do, nether will perform at their best. Either hook the choke up to the stator terminal on the alternator as Ford did which is probably the best way or a switched power source with a relay with power coming off the battery, fused of course. Don’t use the wire harness in the car.

Yeah, I never had to touch the choke.  It worked perfect right out of the box.

It will definitely run out of the box, and pretty well, but I'm at low elevation and it was a bit too rich out of the box for my A code 289.  The stock carbs on those engines were only 435 cfm.  Pretty sure I'm two steps lean on the primary and one on the secondary from the factory calibration.  I like that setup, and so does the car.  The factory setup had it reeking of fuel, and it felt like I was giving up power over where it should have been. 
 

IF, indeed, the auto choke model is the "emissions carb".....go with the manual choke model!  Your 289 will thank you and manual chokes  are for MEN anyway.

Oh 6sally6....

I'm so disappointed!  Chokes in any form are for little girls aren't they?

Here's how it works on the Edelbrock: I never touched the choke.  Its set how the carb came out of the box.  Three pumps of the accelerator pedal and it fires.  Idles at 1250RPM (where I set the adjustment for fast idle on the linkage).  Once warmed up, tap the throttle once and it idles at curb idle.

You guys are wasting gas.  Turn on the electric fuel pump to fill up the carb float bowls, cause it all leaked out since you haven run it in a week. ( I forgot to mention that earlier ). Pump the throttle once. Start the engine, 1200 RPM. Tap the throttle once and it falls to 900 RPM. Put it in gear and bac out the garage then go. Stop at the STOP sign, don't run it. Idling 750 go to the next corner and turn to go on your way don't floor it, it's still to cold it might backfire and quit. Floor it at the next stop light then turn off the electric fuel pump.

Oh, so the Edelbrock is blasphemy, but an electric fuel pump is one of the seven sacraments?!

What is this new age religion?  We just make it up as we go?  Do whatever you feel?

 

Yeah...pretty much!
