I don't have the right resources handy to verify it, but I'm pretty sure a 3600 came stock with 8-lug wheels. If you can find a copy of the 1951 Restoration Pack it will confirm (or deny) that. Look in the Tech Tips to learn how to get one if you can't find one online somewhere.
I have one at home, but I'm about as far (Orlando) from home (Seattle) as I can get and still be in the continental US, so that doesn't do any good right now.
Provided I'm right, the significance may be only that its already got a modified drivetrain, so your modifications are not 'ruining' a stock truck, only making it closer to what you want it to be...
