Mine was modified (not by me) as Greig says. Chunks taken out the sides leaving the bolt holes as mounts. The corners are radiused on it. I have no idea how much weight that saves or what the effect will be in the car. I did have everything balanced though. I think that is definitely worth doing and I'll always do that on an engine I am building now.
