Question Cylinder Honing

Hi, so I am working on my 302 motor for my 65 mustang. I noticed that I have a small ridge on the top of the cylinder and was wondering how to get rid of it if it needs to be. I am new to this engine rebuilding and heard I can do a cylinder honing to clean up the cylinder but I don't think that would get rid of the ridge.

The motor is already bored .040 over and not sure if reboring it even larger would be a good or bad thing.

Thoughts?

Don't use ridge reamers, they make the cylinder tapered, which ****s up ring seal. If you have a ring ridge, the cylinder is worn and needs to be honed/bored square to correct it.

So honing the cylinder will take out the slight ridge that there is in there?

If it's shallow enough. But if you have to take more than like .001-.0015 out to clean it up, then bore it and replace the pistons. Or you can just deal with compression leakdown if you just need to get it running.

Not sure if 302s like an .060" overbore...maybe if it remains at stock power levels.

Generally .030 or .040 is considered safe max, at .060 because of core shift parts of the wall may be too thin. The tolerances on older block manufacturing weren't as good was what's available today.

thanks all, just stopped off at an engine place and they thought that the .060 over would be fine on the engine. So now I have to think about what I want to do.
