I know of the duplicate port connection behind the intake, next to the idiot light sender mount. That’s where I installed the oil tube for the oil pressure auxiliary gage on my 67 GTX. Now I’m installing one on my 66 Hemi Satellite and as difficult as that area was to work in on my factory air GTX, it’s a nightmare on the Hemi with the intake heat pipes. I would at least have to temporarily remove the right side one if not both. So - wondering if there might be another block oil gallery plug location elsewhere on the block that I’m not aware of, that might be easier to get to?
thanks
