I recently bought a 1966 289ci engine (used).After bringing it home and inspecting I found that a rod had broke and broke a peice of the block in the cylinder. The broken area is about 1 1/2" below the bottom of the stroke. Would it be worth sleeving? Or would you recommend a 302ci. I know the 302 will produce more power but I like the originallity of the 289 block. Any suggestions?
