Hi I am unfortunately having to get a new long block for my 2006 Four Winns 210 Horizon. It currently has a 5.7 Volvo Penta Gi-F motor installed and a broke crankshaft to go with it;( . I have been looking at getting a long block to swap out with the old one. Due to the fact I am not really up on a lot of motor work I am going to have to bring it to someone and let them do it. This is what brings me to my question. As I have been looking up rebuilt blocks most of them are Vortec and some places ask if they are one piece main seal. Will a Vortec work for my motor? I hate to order it and the mechanic tell me it wont work or it will cost alot more to use it. And how do I tell if my engine is one piece main seal or not? Thanks for any help
