Can someone tell me why the 4WD trucks have a hump in the transmission tunnel where the 2WD units are flat? Is the engine higher or further back on 4WD trucks. I'm building custom engine and tranny mounts for a LS2 setup in my 4WD truck but I kinda like the flat floor on the 2WD trucks. Seems like it would be easy to drop things down enough to clear the 2WD tunnel.

Thanks.
