I am curious to know, after reading another thread about the turbo interchangability, it got me to thinking... What would interchange from a 24 valve enging to the 12 valve? I know the injectors are on the wrong side, but would the head interchange? How about the blocks? Internals other than pistons the same? I'll sit back and read!!opcorn:

If you do a search there are a couple of threads about putting 24v heads on 12v blocks. The blocks are basically the same, some late 12vs had the STORM block with two oil drains, similar to the 24v and CR block. The blocks, and rods have been slightly changed and updated over the years. The crank I believe has stayed very similar.
