IMPORTANT NOTE
When converting early Windsor blocks to roller applications using standard style factory drop in roller lifters (5300H), you will require a camshaft with a smaller base circle. This allows for the lifters to remain low enough in the bore to not expose the oil band in the body of the lifter at full lift.
These cams will be ground to order so please allow at least 2 weeks lead time.
If using Tie bar style lifters (5351H) a standard base circle cam is suitable.
FIRING ORDER 1, 3, 7, 2, 6, 5, 4, 8
