Well, as some of you know I just grenaded my new World blocked 572 a couple weeks ago and destroyed the block. My engine builder called me Monday and during the conversation he said the main caps had been walking and galling pretty badly. He wondered if I was running bad gas or way too much timing but that's not the case. The timing never went over 33 degrees this year and I run K&S 120 (114 octane) race gas.

Now I suspect my motor had the low quality studs in it also. I can't ask him to look at them until Monday but I bet that's the deal.

I need to buy a new block and now I'm wondering what to do. A lot of you here on Moparts say to go with KB but there's some serious drawbacks to that block, at least for my particular setup.
