This is going to be a daily driver. I think I will be able to adjust my pinion angle because I have an adjustable 4 bar setup. The 'tunnel' I am not concerned with because this is a complete ground up build and I haven't got to making the floor yet.

One would think (??) that the design of the motor would be designed to saftly operate as if it were being driven like comming out of the smokie mountians. It would not be unusal to drive going down hill (or up hill), for an extended length of time.

This may be a good question fon an old GM design engineer, but unfortunately I don't know any.
