I cn't seem to figure out my engine numbers and dates. I have a 235 engine, but it has the "captains bars" on the block. (thougt that was for 261) Behind the distributer is LAQ123413, behind the starter is Con B273, on drivers side of the head is (I think from what i can read) 3701887. I've looked at several sites for numbers but can't seem to find these. Any help from you pro's would be appreciated. Thanks!!
