Ring gap for boost...but running NA I’m rebuilding a LC9 5.3 for a LS swap. I’d like to eventually put some boost to this engine, but I don’t have the budget for it right away. So I’ll be running it NA for a while. I’m thinking about setting the ring gaps for boost right off the bat here in the rebuild so I don’t have to tear the motor down again once I add the boost.
Are there any significant negative side effects to this?

You might have a tiny bit of blowby, but not much--depends on your gap. Most of the time, even on a blower motor, it is not in boost most of the time. Run a good catch can meant for boost. I made sure and set my oil rings at .015 gap.
