Thanks, Bill, that's exactly the kind of information that I need. I'm leaving the choices of which cam, valve train, heads, etc. to be used to the builder since I really have no experience to call on other than input from people like you who know something about all of this. He has guaranteed at least 400 hp and 400 fp torque at the flywheel, so I'll let him build it as he sees fit. I've just never heard much about the 351W other than the earlier years and I need to know what might be different about a 1989 block that would make it better or worse. I can't believe Ford didn't make some changes to the block by 1989, twenty years after the engine first went into production.

Thanks again for your help.
