10k is the stuff of dreams...or 4A-G's and B16's. Youre not going to make an engine like this spin to 10k because the fact of the matter is that turbo or a procharger would be so much more effective cost and output wise. So lets drop that stupid argument.

As far as putting it into the 240? Do it. If you have the engine, and I assume you paid very little if anything for it, then go for it. Frabrication cost is moot at that point because you paid little/nothing for the engine. So you are ahead of the game already. All you would need to do is come up with mounts and a driveshaft. The rest is wiring. Unless of course, you cant live with auto, then its more complicated than just that. But Im sure theres a way.
