Hello, my name is james and i'm an owner of a 1990 ford econoline E-150 1/2 ton van. it has the stock 351 in it and i want to put a 351 cleveland inside later on, my question is, will that motor fit? i was told yes but i just want to make sure before i go wasting money. If someone could help me with this, it would be much appreciated. thanks

later.
