Well, I have a 3.0 with a cracked block. Good internals, been epoxied. good compression etc.. Was looking for a good block to just swap everything over when I came across this 2.5 for a deal. I'm thinking just ditch the whole block swapping idea and just use it for what is, a parts motor. If I do rebuild the 2.5 head how hard is it? Special tools required? Are the valves easy to find/expensive? Thanks for the help.
