Question about .030 bore

[Stomp]

I block is .030 over. I want piston rings that are .030 oversized and standard pistons or standard size rings and .030 pistons?? I'm a little confused.

[Stomp]

Thanks

Kinda confusine.. but you cant put standard rings on a .030 over piston can you... so you will need both to be .030 over...

Confused me the first time i had to think about it a long time ago too...

The .030 has a bigger diameter too. If you put a standard size ring on it would have a wider end gap. Imagine you have a ring that will fit on your pinky, if you try to slide it on your index finger, its not going to fit, you need a bigger ring.
