I know the 600 Ed used carb I have is too much but I have it in my parts stash. Maybe I can trade it for a smaller one. Main reason I like the aluminum intake is easier for this old woreout man to change on that engine sitting in that car!! I will post a wanted ad here and see what appears!!!
I agree with the other post about the 600 cfm carb. The larger primary over the 500 isn’t a gas waster but a throttle response and power improvement over the 500. In other words, it just simply feels better when you press the go pedal.
I have a dead on its heels no HP making smog era ‘78-B 400 (that was running excellent but crap for HP) that I tried a small primary TQ on top first. Figuring the low power smog engine probably wouldn’t need that much carb. Then I made the switch to the larger primary TQ. Gas mile didn’t change but the throttle response picked up SO much I knew that was the right size primary for that engine. Judges gavel slams down, the bigger primary stays! BLAM!
