455 G-body questions

Hello, I'm new to the forum, but I'm an old-time hot-rodder. I've done engine swaps before, it's time for me to do an Olds engine swap. I've done some searching and reading here already, but I have a few questions. My plan is to put a '70s 455 in an '86 Cutlass. The engine is an F block, with J heads, can anyone tell me if this is a factory block/head combo and if so, what years this would have been available? The motor comes with all the accessories, manifolds, and block mounts. The car is an original 307 with no motor in it currently, so I'm guessing only the frame mounts. It appears I'll need a set of 307 block mounts to make it work, is this ANY set of 307 block mounts? I also understand I may need a trans crossmember from a 200-4R, what sort of a donor car am I looking for?

I'm just going to be putting this together to make it work first. Once I have it running, I'll worry about things like radiator, axle, etc. In light of this, any advice anyone can provide regarding this particular swap would be greatly appreciated. Thank you!

You're on the money about the engine mounts.
