1965 273 Charger Carter Carb

Mike, I bought a rebuild kit for the Carter, but the throttle shaft is so sloppy I'm not very confident in it. I also have an extra Eddie 1407 but maybe you mentioned having to modify the stock 4bbl intake. What needs to be done in that regard? Thanks
You'll have to try the Edelbrock on your intake. The secondary butterflies may not open because the holes in the intake aren't large enough.
