I used to have a 36 degree banked tri-oval, and it took a lot of motor to be competitive on that track. Our flat oval has really simplified the rule book. With zero banking, and the whole track being only 6 feet wide, the motor becomes irrelevant after a point. In one of our divisions, we've had a range of motors from 20k to 60k. If the lower rpm hook up well, they stay in the throttle longer on the 12 foot straight (needing less barking before the turn). It really evens things out.
Having said that, at our old banked track, my restricted stock car division used to run the track at about 30 actual miles per hour. The hot rod division, using 4.5" wb chassis, used to create a breeze when they all bailed into turn one together. if I had never had the banked track, i would want one pretty badly. Now that I've had one, I really like the flat track. Gimme another ten years, and I'll be telling you how much better whatever I'm running on then is. It's an evolutionary thing. Just use the space you have, leave some room for pits, and enjoy it until you don't. Then, make a new one.
