3 or 4 inches is wider than the ribs so I would have to chisel a lot of material. How do people do this? with an hand chisel and hammer? I could see this taking hours.

Just drill several holes with a hammer drill and a large drill bit than place cover over the holes you have drilled. It is not important to remove all material as long as you have some good air flow.

I have done this many times with a hammer and chisel. Make a templet 1/4 inches larger than you need. Drill a single hole through one side only. Probe with a stiff wire first to make sure there are no water pipes. Then continue on through. Use a long sharp chisel and a small sledge hammer.
Center the templet directly over the rib. You only have to break one out completly. That's easier than shaving two of them. It's a 40 min job.
Score around the mark with your chisel and hammer on both sides before you break it out.

Try using an impact drill. Drill a series of holes, then punch out the material between the holes with your chisel. You can rent an impact drill. You will be amazed how fast the drill will go through the block.

It is time consuming but cheaper than renting a masonary core drill. Mark out the hole and go around it with a chisel. Keep going around it until the chisel goes through.

the hill billy way...
get a masonary drill bit from lowes or the home dopt. use a pattern with a sharpie marker to mark your hole. drill a bunch of holes all around your mark and the smack the center with a hammer. you can use the hammer to chip away and jagged spots left over...fill the hole with some "great stuff" or something after you are installing your dryer vent or what have you, to fill in any gaps that may left air in

Hire this task out to a concrete coring company. It will be worth the money. You could rent a demolition hammer too but it still is tough to geta clean hole quickly.
I am a plumber and have tried various ways to get through block and brick walls.

Hammer drill. Obvisouly you do not have one. You can rent one from almost any tool rental place.

get a strong stick and spin it really fast in one spot for a very long time, then move it over accordingly until the desired width is acheived.
