OK here goes, you are mostly correct...
Motors-
Stock- Roar (most common standard) 27 turns, of 24 guages wires, one single wire wound , timing locted at 24 degrees. Bushed cans only.
IFMAR (outdated and rarely used any more) 27 turns of 24guage wire wound single, 36 degrees of timing, bushed can.
Spec- 19 turns, single wire, 24 degrees of timing, bushed can
Modified- any motor not conforming to the above mentioned specs
Your motor- 19 turns, single wire, 0 degrees of timing, bushed can.
In theory your 19 turn should be faster than a stock motor.... however you haven't taken the amount of timing into effect. With 24 degrees of timing a stock motor creates a ton more horsepower and slightly higher RPM's, so a stock motor will be faster than your motor, however you won't get as much runtime out of a stocker.
When geared properly there should only be a few MPH difference between a stock motor and the hottest modified motor, but where mod becomes much quicker is the rate of acceleration.
