Hey guys, I was doing some research and couldn't really find a good answer. (Don't bash please). My block is getting bored .020 over, so I'm wondering what brand/size I should get. I heard some people saying stock is good up to 86mm. Then cosmetic makes a 85.5. But not good quality. So my question is what should I get. Goal for the car would be 600-650whp. All answers are appreciated
Thanks,
Dain

 

I would Run Stock.
