big block center link?

For a '69 dart, were there different centerlinks for /6, small blocks, and big blocks? I'm pretty sure that 383 darts had different centerlinks, but for a /6 and a small block are they the same? What happens if you use a /6 centerlink and install a 383? I am considering putting in a 383 in an original /6 dart, that's why I'm curious. Thanks
