I ordered all my misc. Mitsubishi parts and gaskets from Conicelle on Wednesday. This morning a recieved a FedEx box containing my order complete as requested!

BTW - Because I had to have the crank turned down .010 I am having to use Clevite bearings that I'm getting from Winner's Circle for about a quarter of the price of O.E.M. So after putting these bearings in correctly, I'll test them to their limits along with a turned down crank and we'll find out first hand if there's any truth to the Bearing and crank myth.

Well heres another batch of unsubstantiated information to add to the confusion that causes these myths.

My engine builder told me that the crank hardening can be as deep as .018 into the surface of the crank. Obviously this level may vary over the surface area, but if true would mean that a .010 under crank is still ok.

Odly, I've also heard that some of our DSM hero engine builders regularly use turned down cranks in the engines they build for customers. Again I'm not trying to say anything bad about a company so don't take it that way. But if Buscher and Shepard among others really do use turned cranks in rebuilt engines then I'm sure their good enough for my uses.

The DSM comunity always seems to take the most conservative view on all things that could ever possibly break. I mean how many domestic V8's, 6 and 4 cylinders do you think are runing around out there with turned CAST cranks? There is probably more High HP domestic engines with turned cranks than there are performance DSMs all together. Plus I don't see a crank actually breaking because it was turned down unless there was already a flaw in it or there was some crazy engine wrecking explosions. The only thing I can see the lack of hardening do on the surface of the crank is to allow wear and eventually rod knocking or crank walking.

I'll be following this up with more factual information...
