Thanks for your concern. Really. Most of what you say is correct. But there are a few things you are not aware of. Like I own a fabrication shop. Like I've been doing engine conversions of widely varying types for 30 years or more. So I'm completely familiar with what you are saying and see this as not that much of a challenge. Same engine family, the differences are likely to be minor. I'll have ample opportunity to compare bosses and pulleys and back-plates and such. Long as the plate bolts up to both blocks the bellhousing is no concern but the crank dampers will have to interchange for instance. The mounts... well, not that big of a deal really. And considering I can take a tank of compressed air to the P&P yard and run a leak down test before pulling the engine to make sure of getting a good one, I really don't see where this cost is going to come in. I mean, a guy in his 20's who could put a Datsun 1100 in a Cub Low Boy lawn tractor could surely put a Mitsubishi engine in a Mitsubishi forklift, wouldn't you say?

But for most, yeah. You are exactly right.
Jim
