3D models

First time to write in here...
Doesn't know is this correct place for this my question...
So, my project is LS swap to -84 C4 (LQ9 with LS3 heads + 4L65E etc.)
My problem is that I work a lot with Autodesk Inventor and of course I would like to make nice plan, all needed parts (engine/transmission supports, accessory supports...) ready before I get new engine or take old away.
And for that I have tried to found 3D models for components.
Engine model I already have (LS3), but haven't found transmission or any other C5 Corvette.. Chevy parts what going to use.
(files should be .step, iges etc)
Does anybody knows, can those be found somewhere?
For engine room, transmission tunnel... I will make 3D scanning, so it would be nice to do everything ready on screen.. then doesn't have any big problems what you don't know or already clarified those problems...

And when it's done, I think, no problem to share models to other users here

Engine I did found... nothing else

3D model from LS3

And now I'm asking models for LS3 + 4L65E + LS3 Corvette parts, those are not so old. And as did write, I'm going to make scanning for car

4L65E is coming, so should like to get model for that and for TH700r4.
And models should be quite accurate, to see how there is free space on tunnel and how support will fit...
