I have spent a lot of time looking for the warp whistle but I'm starting to think that my game is broken. I used to know how to get it but now Mario doesn't fall through this white block thing anymore which is the only thing I still remember.

There are 3 Warp Whistles in Super Mario Bros. 3.
The first warp whistle is gotten in stage 1-3 by hopping on the white block, then pressing down for several seconds to drop into the background, then running all the way to the end of the stage. Be aware that you need to hurry as this effect does wear off.
The second warp whistle is in World 1 Fortress. You need the Raccoon Leaf to get this one... At the end of the first area, instead of going through the door, stomp the dry bones then run from the far right side to the edge to build up speed so you can fly. Fly up and to the right. You'll land on a hidden ledge above the wall. Run to the right and then press up to enter a hidden door with a chest with the warp whistle in it. Note: This completes the fortress, but doesn't remove its door on the map.
The third warp whistle is on the World 2 overworld. You need to get a Hammer by defeating one of the Hammer Bros. sets wandering around the map. Once you have it, go near the rock in the upper-right corner of the map and use the Hammer. It will break the block. Behind the block is a wandering Hammer Bros (Fire Bros. specifically). Beat them to get the third whistle.
However, you only need two whistles to get to World 8...

And by door, I mean the one south of stage 1-1. These doors are used to continue more quickly if you lose all your lives as all the levels you completed are reset on death. Commented Oct 23, 2014 at 19:46
You're talking about Stage 3 in World 1. Close to the end of that stage, you'll see a white block, like this one:
Holding down on it for 5 seconds will drop you through it, and you'll be in the "background". You can still get hit, though, so be careful!
Once you're in the background, run to the end of the level, and "behind" the black border. It will teleport you into a secret room with a chest that has the Warp Whistle.

Was there some kind of in-game hint or clue that would make it possible for a player to know that this is possible? Commented May 31, 2019 at 6:35

Original: Also according to the letter in W6 it says that there is a whistle in W3 (that is the water world).I didn't take time to find it because I am too lazy but I guess it has something to do with the boat... Also I think I remember watching a video with a warp whistle and it was different from the well known ones. This adds up to five warp whistles if the two I was talking about were unique
Edit: So in the NES version it says W3 but actually it meant level 3 in world 1 (I played Super Mario Advance 4 to find that out) which was already covered and the video I was talking about was the secret box glitch which only works in the Japanese version. Here is the video
So really including glitches you can get 4 warp whistles.-
1Please provide evidence for the existing warp whistles, like a link to the video. In it's current form the answer is just speculation and not helpful.– raznagulCommented Nov 11, 2020 at 12:01
