Post going .060 over , problems?

I just got my 350 back from the shop, the man said he had to go to .060 to clean up the 4 inner cylinders. My question is, should I expect a life long of trouble with this block due to the .060 over bore? What , if any problems should I expect.

Thanks in advance for any responses.

Paul

I know a few people that has went 60 over and as long as your cooling system is good, you shouldnt have any problems. HG

Check under your timing cover to see if you have a high nickel block.Cant remember the exact #s but 421 and 520 come to mind.I do know 010 is a soft block. The high nickel are supposed to hold truer cylinders and have longer bearing life.

Thumbs up

If it has 10/20 under the timing chain cover, or even just 20 it is a high nickel block. If not under the timing chain cover check the back of the block under where the flywheel goes, sometimes its there.

Shouldn't be a problem unless you have a block that had excessive core shift during casting. You can check by examining the coolant holes at the front of the block where the water pump bolts on, if the holes are offset from perfectly center this will tell you how much the core shifted.

The hole should be perfectly centered in the boss. This is not a big problem usually but I have seen a few with 0.030" shift towards one side, measure with a vernier to the edge of the boss all around. *CAUTION* This is not a foolproof method.

The best way is to have the bores checked with a ultrasound thickness gauge to see how thick they are all around the bore, I would be worried if they were less than 0.150". Make sure to check all the way to the bottom of the bore too, remember cores can shift in three dimensions.

0.180" is better and perfectly acceptable. Most small block Chevy's can handle overbores up to 0.080" with no problem.

You can also look at the cam hole and see if it has a equal amount of metal around it (centered)not offset to one side.as long as its centered you should be alright,but if not (Beware)!! (wrenchturner)
