Oh wow... I didn't imagine it being that much of a difference. O_o But that is true about regaining some balance with the V8 up-front though.

Yeah, extra 30 for the diff, 10 for the beefier axles, 10 for the mount, probably 50 more is pretty accurate.

You can shave that quite a bit going away from the iron 8.8 as ZX mentioned above.

Obviously... Thanks for the tip/information Stein.

Another benefit of the aluminum housing over the iron housing would be better cooling. Aluminum conducts heat much better than cast iron and from what I have read differential overheating can be a problem with a track car.
