The LS2 Corvette wet sump is the best clearance you are going to get without going for the dry sump.

I picked one up a while aback and the bottom of the sump is flush with the bottom of the bellhousing. The Camaro/Firebird sump is close but it slopes down towards the front of the reservoir because the motor sits up on a bit of an angle. The Vette sump is flat because the engine sits level.

The Corvette sump also has some really good baffles and a full length windage tray/crank scraper.

I'll see if I can find a pic.

Cheers
