I am restoring a 55 T-bird.  I stumbled on a 57 292  I can pick up for cheap.  Complete motor and cruise o matic.  I am a bit of a novice about yblocks but my research indicates I can gain better heads, rocker arms at the very least over my 55.  Am I all wet? If not are the rods and crank a better option than on the 55 or are they the same.  Seems like at worst I will have some spare parts in case I discover a problem with the original motor.  Thoughts/Advice
