This is some info I got re Mega Block test. Bore 4.565...will be short trip street use, and up to 6300rpm race use, 1/4 mile. But what are your thoughts on more serious drag race use as the motor is very mild currently and only 10:1, max power is@5600, max torque@4400. Motor is built and going into car and will not come apart now.
