Boring question
 

A few years back I had my block bored .030 over for my 3.8 project. I had pistons ordered in for that , buy came as .75mm. Now .030 in metric is .7619, and .75mm is .0295. Will my Pistons be compatible with the boring size I gotten, or is that too large. It's not that big of a deal, worse come to worse, I'll have Ductile sleeves pressed in and have it bored to the appropriate sizing, hell I just might even do that anyway, but it's something that is on my mind at this moment, and wondering if anybody ahs any input on this. thanks.

Wouldn't the ring take up that gap?

That's what I'm assuming, I just wanted to make sure there isn't too much clearance between the piston and cylinder wall that may give me piston slap.

I would measure the pistons themselves. I'm no engine builder but that seems pretty tight. Google it even, there are answers on the internets.
