I'd pull the motor, install a 4.0l from somewhere and try to sell the stroker motor for the cost of whatever the 4.0l costs you. I bet you'd come out ahead and it takes away the headache of having two motor swaps going on in close proximity to eachother.
Hell, contact Dinan they might have a lead on somebody who wants it. It's in his interest to keep the resale value of those motors healthy. They might even be willing to market it for you. "This motor was only used on Sundays..."
