I agree with Dunfire. We use freightquote.com daily. Make sure that the company that you choose has a facility in the location that the engine needs to be picked up and where you need it delivered. I shipped an air compressor from Amarillo, TX to Tipton, CA that took 32 days to get there using Southwest Motor Transport. Try to stick to a well known freight company like ABF, FedEx Freight, Central, Roadway, ect.
