The tires are tall, I would use the 4.11's. Why shorty headers? what chassis is this.

i believe the drag strip on the island (outside Victoria) is 500ft. You want lots of gear on a 500ft drag strip.

The hiway cruise rpm will be just right wiht the 4.11's and 27.5" tires.

3000 rpm @ 100 klicks. This cammed engine does not want a slow cruise rpm.

crusing at 3000 rpm, @100Kph is just right for this motor.

rpm / gear ratio x tire diameter x 336 = speed in MPH

convert MPH to KPH x 1.613
