No bridge ports were allowed, so some clever folks came up with a finger port.
Think about that for a while.

for everyone else the rule said something like, you may port as big as you want as long as you do not change the number of ports (ie with a bp you add a port), crazy stuff

I'll think about the finger (peninsula) port for a while.
Oh my goodness; is it what I think it is?

The beauty of IMSA was the nearly nonexistant rule book. No additional ports. That leaves quite a bit of room. I ran a big street port in RS, and we got to see the leaders many times in a 3 hour race as they rocketed by. Mostly Mazdas.
THe BF Goodrich tires would last all year. If you finnished the race they gave you back more than the entry fee.
They would tear down the first place cars at the next event. ??????? Hey, that makes sense. So everyone could cheat as much as they wanted. Could do anything as long as it was not dreadfully obvious. So you pay people to finish. And you can do almost anything you want.
The point was that spectators want to see many cars racing, not 5 or 6 in one class. So they got what they wanted. We started 67th out of 67 cars in our first ever race at Road Atlanta. I didn't know about that stock 4 BBl in the RX-2.
Jim Downings crew took pity on us and helped with the carb setup. We had 19th in the bag when we pitted for fuel late in the race. We finished 23rd, of 60 cars.
There were as many finger port styles as there were people doing them. I don't know if IMSA ever made a judgment on them or just gave up on enforcement.
A "J" bridge port with one, or two breaks in the bridge, and those segments supported on sections of iron extending into the port from the inside wall of the runner. The area between the "flying butresses" was the added port area. So long as the corner seal didn't fall into the port (the object of the bridge) it ran fine.
Like one or two fingers reaching in from the runner to support the corner seal.
