Sounds like I must be the only test case for this. I got my 410 out of a 67 Mercury. The story I was told was that it was an engine used only by Mercury for the Maurader? and one other boat of a sedan. The nice thing was that it had the correct casting numbers on the block so I rebuilt the entire engine, changed the heads to match the ports on a factory PI intake, put in a CJ cam, and ended up with a nice factory looking setup. I had the assembly balanced and the walls checked and all was found to be ok. This was done in 93 before the internet and alot of the current stroker motors. I recently resumed the construction of my EM kit and hope to have it done by the end of the year. No real time on the engine other than the ocassional startup to keep the fluids running. The stroker is probably the way to go, but I had to have a PI 428 in my car. Good luck with your choice.
