1.5d is a 2700kv motor isn't it? And 6 A123 cells would be 19.8v?
I would think that motor might be a bit hot for that voltage. Potentialy around 50 000rpm, which is a fair bit for a monster truck. It would work, and be very fast, but personally I wouldn't use that setup for more than a one off speed run other wise I would think that you'd have some heat problems.
One of the lower kv 1515 should work a bit better.
For racing monster trucks most people aim for a motor/voltage combo that will do 30,000-35,000rpm to get a happy medium between heat/speed/reliability/runtime etc.
You can go with a setup outside of that, but usually there will be a trade off between those things.
