Can this be done with out changing a bunch of stuff? Is the gear ratio of the outdrive concern? I was told that it would be no problem to do this and the manifolds would interchange as well as everything else..?<br /><br />Give me some feedback

As long as your goig back with a 89 or so 5.7 dont try it with a brand new engine theyve changed quite a bit.
