Hi. Well this is my first post, so dont if its the right place?

I've been looking for a replacement engine for my car and found this 351 windsor:
351W
Anybody know the company? Comming from Denmark so i just wanna make sure that i can trust the firm, since there is a long way if there should be anything wrong. Is it a good price? If you know any others who sell complete turnkey engines, let me know. Been looking a bit at Jegs, is that better?
