Yeah and it concerns me a tad bit too. Older BBC's were fairly notorious for holding oil in the top end. I am hopefull they improved this situation on the Gen V and VI designs.

It is very low profile though. For my Gen VI 502 I went with a kick out style 6 quart Moroso pan at the recommendation of Salley chevy.

Chevy would never sell us a pan that let us burn up our motor, would they?
