About two months ago I purchased a electric choke kit from Speedway Motors, part number 427-45223 for my 600cfm Holley.
Two years ago I got this sweet deal on a new manual choke Holley 600cfm carb for $200 so I replaced my Edelbrock 650cfm. Very noticeable difference in performance running the Holley. When I purchased the truck it had a Holley 750cfm double pumper, but it leaked and needed rebuilding so the Edelbrock 650cfm was installed in 2004.
With all the bodywork and smooth firewall I had to add the electric choke to the Holley since the manual choke cable is gone.
Overall installation took a hour.
You get all this in the kit.
Before starting to take things off.
Pretty easy instructions to follow. I have to use the old spring but install a new idle lever. It has a different angle with the adjustment screw.
Pull off the post.
After placing the new idle lever the base of the choke is mounted using the screws supplied with the kit. After, you want to make sure the throttle plate moves freely, and recheck your work.
When installing the cap you have to place the coil loop into the tab on the base. Install the three screws and turn the cap and watch the throttle plate close and open. Set the cap with the notch on a line on the base. The plate should be closed position. I will need to watch for proper opening as the coil warms up and pulls the throttle plate open. Additional adjustment will be needed then.
Got the ground connected and the 12v side. I had never removed the old hot when I removed the Edlebrock so I was one step ahead.
