this could happen if your timing is way off (way to advanced) or your timing chain could have jumped a tooth or its just really stretched out and in need of a new one, could also be from your valves not being adjusted correctly. most likely a timing issue though, i'd check that first before ripping it appart to check more severe problems

What would cause 85 Corvette to backfire through intake?
Several things can cause this. Low fuel pressure due to faulty pump or filter or injectors, inaccurate ignition timing, wrong spark plug routing, intake valve not fully closing, excessive carbon on the intake valve, sometimes it can even be as simple as bad sensor. Those are general causes. Corvetteforum.com is a good resource to discuss with fellow enthusiasts.
