This is the second generation block I think now they are on the 3rd.. it is cracked in the cam tunnel I am curious to see if others have this issue as well we have made decent power with this block and beat it pretty hard.. the crack opens up allowing the cam bearings to slide out with heat also allowing water into the oil I didn't want to scrap the block just yet so we're trying to stop the water leak with some epoxy.. the first generation block that we've machined turned out to be a total piece of junk and unusable. This current block is at 55mm.
. I believe there is a major design flaw in the cam tunnel area but we will have to wait to see what develops with the others that are being built at this point in time
