Opinion: Small motors more or less consistent than big motors?

I would go with the more cubes the better idea, the motor needs a little bit of a load on it, they aint happy just freewheeling. My 440 would run the same number from the first time trial to the final round unless they was a huge weather change comin, smart bracket racers have their own weather station to keep an eye on. I ran two cars, a 67 cuda with 440, transbrake, throttle stop, 4 stage timer/delay box and a 23T roadster with a 350 chevy, transbrake, throttle stop, 4 stage timer/delay box in it also, the wife would drive one and me the other, the smaller engine was harder to make consistant in the 1/8th but was deadly in the 1/4. Suspension is also critical for consistancy as is doing the same exact thing time after time, if one thing varys then something is gonna change and its usually the ET.

Man I love bracket racing, it gives an amature an even playing feild against a professional big money car in the other lane.......all comes down to your skills.
