351w #1 cylinder, .350" down the barrel, $3k for block & rotating assy, $200 shipping, and 120 miles round trip to pick it up, and this shows up. :CRY:

no raised nicks or edges, i think it is where the piston ring was located when it sat previous to the teardown and machine work. it is .030 over now, i don't think .040 would have cleaned it up. carl at cnc said he has done a few with no problems, so i guess i'll go with it. keith craft said it was ok also, course his money. just real frustrating trying to do a meticulous build and this happens.

I would run it...
The piston ring won't catch it and it will be fine. It's very, very hard to get a perfect cylinder on every cylinder on every block you come across. |
thank you, everything looks superb otherwise.

If so,I've seen this a time or two,as long as you can't feel it with your finger nail or hang your nail on it, you'll be fine...... David |
i can catch a nail on it, i was wondering about blow by the ring or breaking a ring on it, but a few have said run it, so.......
|
You can catch a nail on it because it's a little blemish, not because it's raised.

I think porosity. I'd mag and sonic wall it. But I agree it can run like that-unless it goes to the core of the earth.

The 351-W block in my street car had 2 marks just like yours,but longer,40 overbore and they still showed,I put that engine together in 1995, still going strong to this day with no problems............

I'd rather not see that - but it ain't the end of the world. Probably rust from when the block sat for an extended period. As long as it pressure checks OK I would run it.
