    I've got mine plumbed where the thermostat housing would go. Made a flat cover, drilled & tapped for the 1/8 npt fitting.

    i pull mine out the side of the block. Between two freeplugs there's a 3/8" plug (think it's 3/8"), put a fitting there. This is on a mark IV 454 block though, not sure if that exists on a 540.

    IMO there is too much debris/sand at that point in the block. Thermostat is the highest point and is probably the best spot(IMO). Sure that spot works, just a potential problem area thats all.

    I see you have an I/O. You can use one of the tapped fittings on your intake manifold in the front crossover passage. I agree, less chance for blockage here.
