Bore Gauge Help

Don't forget to check ring groove clearance on the pistons too. If the rings flop around, there's no point and you could break a ring ruining your block and that's NDG. Check the skirts too. If they're wasted it'll be pretty obvious but measuring never hurts since you just want a short term runner.

It'll run with sloppy bore/piston/piston pin clearance but sloppy ring grooves will ruin an engine block.
