they are usually made .003 shorter than a steel rod. we run our bearing clearances just as we would with a steel rod.

as you know, the block needs notching, and if you are running a girdle, you will need to clearance the girdle.

be sure to tell the company who is building your rods, the size of your cyl bore.
i had a problem with my rods not fitting in the bore...had to send them back to get clearanced to fit into the cyl bore.

from my understanding its a noticeable difference in weight and it will be driven to the track and home from the track.
