670 × 7 = about 4700 rpm, assuming you run it on a 6-cell pack.  You
don't say what the input voltage is for 600 watts, which makes it hard
to judge exactly what it'll do.

By car standards this is extremely slow-revving, so it would probably be
very good for rock-crawling but not much use for anything else.  A hot
modified will run beyond 40,000 rpm off-load, and most cars are designed
with gearing to suit this.

You also don't mention what size it is - 1/10th cars almost all use 540
size motors, so if it's different you'll at least have to make up an
adaptor plate.

If your numbers are right then simple math tells us 7.2v x 670rmp/v =
4,824rpm.

For comparison I have a Novak 5600rpm/volt brushless in my 1/10 4wd
buggy.  5600 x 7.2 = 40,320rpm.

Check your numbers again and if that's right then it won't work.

Your motor as to many winds and poles on it.
RC car brushless motors have only 2 poles.

The motor you have proable has more than then poles.  every poles supplyes
extra torque.  You need revs.
The motor seems more suite to 1/5 Electric car on 20 cells.  they exist
howerver (still ) not really popular
