Damper Location Help Needed

Here's the damper/pulley combination I have to work with. The damper diameter is 7", while the front pulley is 8".

As you can see, the size might create a clearance problem and can't find a clear picture anywhere that shows how far forward the engine is mounted, but with the rear mounted distributor, there isn't any room to move the engine back, or raise it much, so at this point I'm flying blind.

Any photos or measurements that might give me a better idea of the engine location would be greatly appreciated.
