Hey Rattle, that's really cool and ought to hush those guys who get on here and complain every time someone says, "small block Chevy".
I have dreamed about something like that but getting the axles out of an AMC Eagle, S10 Blazer or etc. and turn that Caddy rig sideways, run a driveshaft to each axle and have an all wheel drive.
Hats off to you for having the guts to go there!
