Various Baja 5b questions and a possible new project -

So this goes out to the 5b owners, and I also have some electronics questions for a savvy members...
First I was wondering what a 5b roller weighs? This would be minus the motor, tanks, and pipe, but with the electronics and servos...
Next, the width inside the chassis would be helpful.
Now, on to the power questions. I have a few 1527 motors. I figure that a 1521 will not be enough, but will a 1527? Winds are 2y and 2.5y, 635 and 500kv repectively. CC spec the motors for 2250 watts, or 3 horsepower. Is this enough for the 5b? It is a heavier vehicle than I am used to. But is is 2wd and that will not load a motor as much as a 4wd will. My motors have 8mm shafts, and I have found 1.5mod pinions in 12 and 14t. This will give around 45mph with the 1527 2.5y on 12s lipo.
My battery selction includes a pair of 6s 4500 30c polyquest lipos. These are spec-d at 135amp cont, so at 70% effeciency that is around 5.5hp, much more than the 1527 should pull.
As far as esc choice goes, I am stuck on the hv110. Not sure if there are other choices... Trying to stay around 200 bucks, may even try to scare one up used. I like that esc due to its programability. And it supposedly has a decent startup for an air esc. Now can I safely run it on 12s, or would I be better suited on 10s? Pushing stuff is not usually a good idea, but if it can handle 12s it will save me having to reconfigure my lipos (even though I can do that in my sleep now).
Now at 110amps and 12s lipo that gives about a 6.5hp potential. This has me wondering if I should go with a more powerful motor.
Any thoughs or critism (or just silly pics) will be greatly appreciated. I will examine some other motors and report back. As usual I am trying to keep my costs down, but still have a well performing setup.
