I have a '89 F-250 2X4 with a worn out 302 and have an opportunity to get a wrecked '90 F-250 4X4 with a 351 in it. Both are 5-speeds. Is this an easy swap? I'm sure the ECM would need to be changed, but other that that. is it a simple swap? Are both of these engines Clevelands? Is the bell housing pattern the same as well a motor mount placement?

i would have to say that the engines are not clevelands, being that late a model vehicle there probably a windsor engine, in which case the 351 will probably sit higher in the engine bay as the deck of the block is higher in the 351 so then your intake manifold and i'm assuming efi gear will sit higher also.
