Vince, I don't think the scoops are hollowed out but the big end pins are very close to the edge of the crank. I was thinking of offset grinding. My car engine builder does this all the time. He turned down my big end rod journals from 2.25" to 2" to allow a longer stroke longer rod and a bigger cam without interference. Smile Matt, lets do some grinding Smile Have you ever seen a crank let go at the big end without help from some piston debris. Not to say that it can't happen I've just never seen or heard of it happening. Plus I've got a great machineist who would be happy to whip up some titanium rods if we furnished some to copy Twisted Evil This would add strength and reduce weight Smile
