Thinking of buying a Street Demon Carb...

What I'm trying to do is put the car back on the road after sitting for the last 41 years in storage. The engine is all original and I still have the original AVS carb, but it will need rebuilding. I kind of looking for a new carb that will pretty much work right out of the box for the initial restart of the car next spring. I still want to use the original air cleaner if it will fit without a clearance problem.
Edelebrock has the "Thunder series AVS". That would be direct Replacement-ish?
