Well, mine had ripped itself out a while back, I had the piece welded back on and its been fine for whatever the last 6 months or so.

Wellllllll it finally broke again, and this time, it cracked the block on the other side as well, meaning im out a block. Fortunately, the car only ran for about 5 seconds like that, so im thinking that my crank and stuff is salvagable.

We are going to tear into the car on Sunday, and at the moment the plan is to reuse everything on the car but replace it with a 6.0 iron block, and forged rods and pistons, new bearings etc. I currently have 243 heads worked over pretty good and down to 59cc so that should get me somewhere around 11:1 compression on 4.005 bore, but im thinking about going to 4.030 bore to make a nice, reliable, monster 370ci LQ motor that should work well with my current heads and cam.

hoping to make something like 450 rwhp and 450 rwtq, up about 50/70 from the ls motor, and really ready for some boost with a set of 317 heads later down the road.

So is this issue only on the aluminum block motors and not the iron blocks?
