The Magnum super-ute (the white one) is also fitted with a 5.6L stroker, and was done later than my car, so it would be safe to suggest it should have the same components in it.

You could option the 5.6 into any V8 HDT in '87 & '88. Here's a 5.6L Bathurst for sale at the moment: http://www.musclecarstables.com.au/details.php?id=482
