Of course they are!!
The big Z motor is, IMHO, the strongest, best foundation for a big-bore streetbike. As far as I'm concerned, they're indestructible.
Lots of variations in those final few years - standard, cruiser, 1000, 1100, tourer, shaftie, super-sport (the GPz)...
I'd go for it, depending on how 'loud' the song IS...
