It was a typo. Old and need glasses.
The LS6 is stock. It' rated at 405hp.
The bottom of the car is completely flat. The
oil pan doesn't stick below the frame rails. A full belly pan is possible. But, I haven't done it as I built it to cruise the street. I do have a custom fuel tank and I molded in the bottom of the body at the rear so that its smooth and the tank is not exposed.
The C5 3:42 diff has been converted to take a driveshaft. It bolts into the back of the backbone trans tunnel.
The car has 52% rear weight and is heavy at 2550lbs. I have another car that I built using C5 parts and drivetrain that is under 2000lbs. I built that one with weight reduction in mind. Knowing the Cobra was for the street I didn't worry about the weight too much.
My Cobra tribute is plenty fast for me. And, its a great driver. I have the reliability and repairability of a C5 Vette. With the double overdrive it gets great fuel mileage as well. I know that's not a consideration for most Cobra owners. To me, its an added bonus.
