Being new here and reading what I have on this and other forums about the "Y" EMC adventure, I got to wondering about the bottom end.  I believe I read the EMC engine was capable of 7K + rpm's and I see where a number of you race the engine.  What, if anything do you do about the main caps for durability?  Looking at the current project I'm working on, it struck me that a little creative machining on the block and some spacers, and it would be possible to duplicate the cross bolting process the FE 427 was noted for.  Has anyone tried that?  Does anyone make better caps or does the old motor do just fine once the crank is upgraded?  I saw a spot where the main registers could be drilled for 1/2 arp studs but, given the register width, that seems counter productive.  I'm not considering doing anything with a Y yet, just thinkin.........
