Default Ring gap for boosted 5.3
Looking for some advice on how much to open up my ring gaps on my Incon TT 5.3. Stock block/rods/pistons with ARP cracked rod bolts. What are you guys running for ring gaps? I've done searches and it seems everyone is giving advice for e85 setups or max effort setups. This will be for a 600hp street car with meth.

Thanks!

I'm looking at .025" for the top and .027" for the bottom. Does this sound alright to you guys?

No, if you read up on that junk yard big bang theory engine stock rings but the top two were gapped at .028 and bottomed left alone.

.025 on the top and .027 on the second would work fine, run it.

If you don't detonate then stock gap is perfectly fine.

Rings expand with heat, and if the ring gaps touch, then bad things happen, namely ring lands tend to break loose, especially on stock hypereutectic pistons.

.028 to .030 top .028 second witch is close to stock. Can be a little closer if running e85.

Are you guys experiencing more blow by with the gaps this large? I've got a pretty decent catch can setup so I"m not too worried about it. I guess that would be better than breaking a ring land!
