Hi all,

So I've discovered my block has a bunch of tiny cracks that are invisible to the naked eye (well, invisible my non-machinist untrained eye). There are cracks around the water jackets/head bolt holes where the yellow paint is. 

How common are these cracks and what are peoples thoughts on running this block as-is? I'm chasing roughly 350kw and I'll be using ARP studs, and a Nitto head gasket. 

I'm worried I'm going to get stuck in a never ending cycle of getting another used block only to find it has the exact same cracks.

Find a unicorn NEO AWD block, apparently stronger and cheaper than the N1 business.

I was lucky to get mine so cheap 🥰
