My biggest issue to overcome (big block) was getting the damper to clear the belt drive lock nuts, idler, etc; the large amount of spacer needed to move the damper out was reducing length on the crankshaft.
rebel,
I like some of the features of the Aussie unit also. But the fit problems stopped me from using the big block version. Can you answer the original poster's question, since you are running one?
I used half nylocs on the cam gear to improve clearance from the damper, plus I'm using an ATI damper that has a longer snout on it.
