Sump capacity

[ayjay]

I'm about to modify the sump on my cvh engine.

How important is it to restore the sump capacity if Im only chopping 30mm or so off the deep part of the sump.

I'm considering not bothering with the extension bit of the mod.

Any thought on the matter would be appreciated.

ps when I get someone to show me how to do it I'll post some pics but nothing exciting yet. (how many chassis does anyone need to see!)
