Thermoquad vs Edelbrock

I went with a #1406 600 edelbrock , on my 73 340 , had to change jets and , metering rods , and went with an orange spring in the kit to get rid of hesitation . A stock edelbrock is to lean for the 340 , it was on mine anyway , spacer plate , and you will need a #1481 edelbrock throttle cable adaptor.You can try one stock might be ok, but i tried three different eddy,s andwhen i changed the internal parts , works perfect.
