The block number is 3837012. But I thought the full flow was better? Why would you want the older block? I have the head (and rest of the motor) from the origional '53 235 babbit. If I am going to have the head rebuilt anyway would it be better to use the 235? I'm not sure about a trade Josh but will consider it. I'm just at the "what if" stage. I'm still not sure- can the block I have be made into a full flow?
