The Savage requires a pretty wide tunnel. It has to clear the coil, the turn signal flasher, a couple of bulky electrical connectors, and the decompression solenoid. The frame makes a very wide spread where the single backbone spreads into the two frame rails in the last 1/4th of the tank.
You might be able to make that tank work if you are willing to cut and modify the top frame rail on the Savage, and relocate some of the electrical components that are under the tank.
Here is what I had to do to a Suzuki GT550 tank to get it to sit down far enough on the frame to look proper on my bike - some have left the tank sit up a bit higher and it looks fine. You can see how wide the tunnel is, and yet the decomperssion solenoid was eliminated as there wasn't room for it.
But in order to get it done low enough that the forks would work, I had to do this, and it took about 6 hours of heating, hammering and fitting:
Then once I got the tank to sit low enough, I made the front tanks mounts:
The tank sits lower and the head sits a bit up inside the bottom of the tank.
