I found this great shipping company, its kind of a ebay for shipping. You place your shipping order, and then get bids for shipping it, the lowest bid wins. But the cool thing is, you don't HAVE to go with any of them and the bidding lasts for a couple of weeks.
It worked great for me. I bought a 300lb A518 up in Northern Michigan and had it shipped to Austin Tx for $135.
Its called Uship.com.
By the way, auto parts are class 65, and I think was told motors are class 85. I have no affiliation with these guys, it was just the best way I found to ship stuff.
