Just to put your mind at ease, here is a photo of the underside of a 3.7 Roadster. Taken from the front looking rearwards, you can see just how flat and tucked away the sump is on the 3.7 cars. The lowest point of the car is the dip of the chassis cross member.

Wolf & Brands Hatch Morgan do a 'skid' plate that bolts to this cross member to enable the dip to be ramped at an angle to avoid hitting at a vertical angle, but this comes at a price of a few millimetres loss of overall clearance, so it's a swings & roundabout type of decision.

Hope this helps.
