Intake suggestions for a 440 66 dart

The intake will say if it's a torker, or torker 2 right on the top. If it's a Torker2, I would keep it. It's shorter than an Edelbrock performer RPM. Just get a drop base air cleaner. That will get you some clearance. Putting stock manifolds will kill any power you hope to make. You might as well put a 318 in it. Consider taking off the rusty headers, and take them to the header guy. It should save some money. Also, check the torque converter. If it's stock, it will also kill performance. What are the rear gears? It's the total package that makes a good car.
