Was this a 63 block? What kind of overbore?

+1, too much boring mebbe?

The pic is incredible, I can't believe the whole thing didn't let go. At last you can re-use 90% of the parts!

Mo had a cracked block but his was the 2.4 6bolt block.

John, you don't deserve this kind of bad news. Best of luck on finding a new block and hope to see it out there again in the spring. :D

This issue isn't uncommon with high hp 4g63s. Even ones with 0 overbore.

This is a 4g63 block with un known miles, about 300 miles at ths power, most of which was just driving around. The block was a 40 over bore, they weisco 9.25:1 pistons were shelf stock with the 40 over.

I have another used block, I will bring it to work and sonic test everything I can. The sleeve idea is out, just a partial fill with hard block. If its only the block and everything else is ok it will be running in spring.

From what I recall it was the #1 cylinder that cracks, and some say its from cut driver side motor mounts. Thus why I made my motor mount bolt on to the front of the block also.

Hmm, I've heard of several 2.4's with this, hardly any 2.0's. Sucks to hear, but luckily blocks are still pretty plentiful.
