I'm using a 15T bell I think. That truck has slayer output gears in it, which are plastic, but geared higher than a revo... guessing whatever stock gearing is, you will be able to pull at least 2+ in the bell over stock with a big block.
I'm using alloy shoes as the composite ones slipped a lot with how it's geared. They would be fine for about a tank, then they would heat up and slip. Something like these would probably work better for you:

7075 is hard aluminum. It won't grab as hard, which will help your drive train, but it will wear longer.
You need a proper flywheel nut too. That set of shoes comes with one. The 3.3/2.5 use a traxxas specific one.
The last time I ran it.
