Rover, Schmover! An LS1 Manta!S

According to this righteous Manta's owner, regardling the 3.5L Rover V8, "This is a rather lazy engine which is ready to be removed from the car." And that's just what this wacky Norwegian did, getting permission from the authorities to swap in the LS1 from a Firebird. Now we're thinking dry-sump. Now we're thinking over 400 inches of displacement. Now we're going all batshit-googly-eyed over the idea of an LS7 Manta. Mmmm...
