Alex,
I just looked into shipping an engine from Canada to Cali. (I know it doesn't make sense, the deal tanked anyway).
UPS will only ship upto 150 Lbs.
If you can ship through a company, then you can use UPS freight.
If not, then you are probably looking at having it shipped by a local trucking company ($$$).
To give you an idea: having my engine shipped to Cali would have been US$ 500
HTH
Rob.
