Note: This head was flowed on a 4.250-inch bore fixture. Our 540 sports a much larger 4.50-inch bore that unshrouds the intake valve considerably. This is why our flow numbers are smaller than Edelbrock's published flow numbers.
Cam SpecsThe cam we used was a Crane custom mechanical roller with the following specs, installed 3 degrees advanced at a 109-degree intake centerline.
