I am building a 1955 Ford PU and I am going to use a 351 Cleveland out of a 70 Cougar and I am looking for a plastic replica engine to make the frame set up easier. Anybody that might know of an outlet for this application I would appreciate the furhter information.  

Do you have the engine you are going to use? Is it simply to heavy to use for the mockup stage? I would suggest taking exact measurements, so that it will work with the motor you will be using.  

I do have the engine and transmission. Yes weight is the issuse. I can get the plastic tranny to match what I'm using but Payr, the only outlet I know of, does not make the cleveland block. They only make the Windsor block. I just wanted field the question to see if someone knew of an outlet that I did not.
