finished tearing down my 230 "cold" block afew days ago and noticed afew small "cracks" along the passenger side lifter valley (more like right along the lifters) they are not deep at all. A buddy of mine says it looks like a casting flaw, could this be or is it something i should have checked out?

Thanks Ryan

just shot a coat of primer then he looked inside,
well him and my uncle tore that engine down,
I still remember that rumblin' sound.....

i would have it checked before i built it, that way you aren't throwing good money at a bad block.

here are the pics, sorry for the bad quality but my camera sucks bad...they actually look alot deeper in the pics than they actually are...i'm really hoping this block isn't toast as the rest of it is very nice....this is just as i tore it apart, no cleaning has been done as of yet....

Chances are that is a crappy cast. I've seen worse.. It's hard to really see anything in the pics as the flash is giving us some overkill off all the oil. Try washing down the oil with Alcohol , or carb cleaner, or brake cleaner and dry the area before taking the pics. You should be able to see much better what is what.

Just the same. I would never just slap a motor together without giving it propper machine work. It;s not worth the money you stand to lose. Take it to the machine shop and have them tell you exactly what is what.. :yesnod:

would this be fixable if it does turn out to be a major problem?

Again, that is something best asked of your machine shop.  Seeing something in person and looking at distorted pictures leaves allllllot of room for error.

It is in your best interest to take it to a reputable machine shop and have them take a good look at it. Chances are it is just a casting fart. Let's hope it is and isn't too deep.

my guess would be it is a very shitty casting on the block - we had a 440 block in with similar "cracks" and it turned out to a casting problem - the engine is alive and well making 464rwhp...     no problems in over a year...

that looks like the drivers side of the block , generally the worst side for craking is th epasenger side as the cam rotates cloclwise & pushes the lifter bores away from the cylinder bores on high lift cams with increased spring loads
