what do you want from a carb. The 600 will work but if you plan to use it how you built then that carb wont work. i would guess a 780 or 800 would be minimum and you can probably go much higher.

I'll agree with Antoine, I think I read originals were rated 750cfm which might be a minimum of 650cfm in todays world. Since you seem to be adding performance I wouldn't go with the 600. It does bite not being able to use a NIB just sitting around
