BL Newcomer Looking for Some Kind Advice

The BL bug has got me. I need some help from those that have a lot of experience, and this looks like the place to find it.

I'm working on a BL-LST2 conversion. I don't have the truck yet, just planning the project out. I'd like to start it this coming spring/summer. I have a couple of ideas of what I'd like to get out of the machine and hopefully you guys might be able to point me in the right direction.

Things I'm hoping to attain:
- Lots of low-end power.
- Respectable speed (truthfully 30 to 35mph is plenty for my use).

Things I'm not looking for:
- Land-speed record breaking fastitude.

I really like the specs on the Quark Monster Pro 125b ESC. My biggest "question mark" would be - what's an appropriate motor? I'm planning on running the equivalent of roughly 16- to 18-cell LiPo's.

Is there a Feigao model that would get me where I need to go, or is something like the Lehner 1940 or 1950 more what I need?

I really appreciate any help you guys may have.
