I fear I once again didn't look forward enough and may have made more work for me. I am replacing a 239 Y-block (don't ask) out of a 1956 Thunderbird with a 292. I didn't think to look where the hole for the oil dip stick tube was located on the re-manufactured 292 before I buttoned up the oil pan.

I find the hole on the side of the block for the Thunderbird is plugged, and the hole next to the timing cover is open. Can the plug be easily removed on a complete engine? or do I have to drop the oil pan to remove it? How do I plug the open hole?

Thanks
