Sold my Edelbrock carb when I switched to a Holley but still have the tuning kit. I used one set of metering rods & one set of step up springs from the kit but put the originals back in the carb & the ones from the kit back in the kit so the kit has all the sizes it came with. Kit part number is 1479 & is for 600 CFM edelbrock. Pics below show all the jet, metering rod, & step up spring sizes.
Look to be about $57+shipping on Jegs; let's say $35+shipping.
Sorry the pics are upside down; lost the originals when my hard drive crashed & haven't figured out how to get my own pictures back from Photobucket so I'm just linking to them there....

I won't have any need for it for about a year, and haven't bought my carb yet, but could go $25 + shipping. Would this kit work for a 500 CFM?
I think this one is a bit big for your needs.
The 500cfm Edelbrock is either model #1403 or #1404.
Calibration Kit #1486 for is #1403 and #1404 includes:
-Metering Rods (Pair)
.057 x .049
.062 x .052
.063 x .047
.067 x .055
.068 x .052
-Metering Jets (Pair)
.083
.089
.092
.098
-A complete set of step-up springs
You can see in the pics that ost of the Rods and Jets are on the high side.

I'd agree. The one I have would be better for someone with a 600 CFM carb.
