Cracked mains

Maybe?
I'm curious, as I have heard from some pretty big name guys about the hard block actually causing cracked blocks. I have not seen one personally.
Nope wasn't a filled Block. Crank appeared to be fine but I didn't even both having it checked. I dropped off another block and crank already. The bearings looked ok. It was in for a line bore for main studs and a gridle. I'm glad I took it apart! I had assumed that this built engine had main studs but it did not. I found the cam gear on the crank wasn't even keyed.
I have heard of guys cracking filled blocks. I think a lot has to do with install and prep setup.
Are the filled blocks cracking with or without sleeves? If they've got sleeves it's because they aren't installed right

I think Idaho Rob cracked more than one IIRC. They felt it was due to the Hard block...
Interesting way for the block mains to crack on this one.

Half filled or solid concrete? Half filling is a bad idea and will promote cracking

If it's the one Curtis built for James I wouldn't have questioned Curtis' judgement either. He's built and tortured more duramaxes than I've laid eyes on. still
I figured it would have had main studs for sure. It still had a stock balancer on it. Rods are good. Pistons look brand new. New block has main studs, Wagler gridle, 9100af cam and an ati balancer. Running 150 overs with a gt4718 as a single this season if I ever find time to put everything back together. Will be on the land shortly
