Picked up two Holley #4783 carb's one near perfect and one needs the base replaced.They were in a five gallon bucket one on top of the other the bottom one was at one time in water just on the base. My question is will a AED6450--500CFM base work on the #4783 carb ?
Thanks POPS
 
Are those the direct connection mechanical carbs? If they are, I'm not sure if they are the same base or not
 
Yes they are direct connection carbs. The base pictured sure looks the same,linkage looks a little diff.
 
Same base,different linkage,getting these back together eventually.

check to make sure throttle bores are the same.
 
No they will not interchange. 4783 has 1 3/4 plates vs the smaller 750 size Bore/plates of the 4412.

With some boring and fab work it may be possible. Your idle circuit is also different.
