And yes I know, the date on the camera is a wee bit off lol

 

you could get it honed and use an oversize ring

 

I already honed it a bit. I dont want to over-do it. Even if I use oversized rings, the piston-to-wall clearence will be too big

 

Hard to tell from a pic but you could take the block to a machine shop and get the opinion of a reputable engine rebuilder, see what they have to say about it.

 

If it is only one score mark then probably it will be ok. You will get a little more blowby. It depends on what you want to do with it. If you are plan on driving it gently for ten more years then you might want to bore it. If you are going to run the crap out of it for a year or two and rebuild it again then I would not get real worried about it. If it is a wide score you may have problems. If it is just a scratch I would not get too worried.

Yeah thats the thing, its not really wide at all, and its not even an inch long. So I believe it should be fine. Thanks.

 

Did you make sure your tolerences are ok to hone and use stock size pistons and rings? maybe you could hone a little more if your tolerences are still good. In my opinion its worth doing it the right way and having the machine shop do the bore while your car is already apart... The last thing I want to do is rip my car apart again cause I wanted to save a few bucks on pistons.
Good luck!

 

Yeah, I t-gauge/mic'd the cylinders and they were like .0002 under spec :dunno: I even measured it several times to make sure I wasn't just messing up. So I guess I'll just hone it till my fingernail doesn't catch, then remeasure it, or just throw the pistons in and check clearences. If it's out of spec, shit I'll just re sell the pistons.

 

Does the mark catch your fingernail if you drag it over it?

 

Read the post thats the first thing he pretty much said in his first post.

 

Ooops, sorry, then yes the issue needs to be addressed. Larger bore/hone.

 

Reliable power is better, my .02.

 

You should be alright, as long as you/your shop doesn't go crazy on the bores. It's where having a good machine shop shines. Make sure they have the right torque plate, as well.
