"Passed blueslip on 1st inspection subject to identity check due to the fact the block had no engine number stamped on it. Im sure RTA in their wisdom will find some other reason to cause me grief!"

There shouldn't be anything else - you have the blueslip and have completed the identity requirement. At the RTA they should just be satisified with sighting the new number - the rest is on the blueslip.
Good Luck

Nowdays when I take a car (project) thru rego, I think to myself, now i wonder what they'll find? they're bound to find something" The car usually sails thru'.

Before, i used to think "this car is goddamn perfect, they won't ping me on anything"
And they would end up finding shitloads.
