Over budget 318 build

Ok that chart can be confusing. Here it goes. Skirt clearance is the difference in size between the block and the piston. If the bore is 3.940 (030 over) then the piston should mic 3.938 If you wanted .0020 of skirt clearance. This clearance is finished honed by your machinist and should be different for a nitrous engine vs an N/A engine. I’m saying I wouldn’t run .0020 of skirt clearance on a nitrous engine with KB slugs. I’d want a little more. Rings are another measurement all together. But the same theory applies. More heat (nitrous)=more gap. Make sense now?
So what you’re getting at is that I can’t just point a finger at any line on that list, gap the rings to it and expect the motor to hold just because I gapped the rings to it and followed that specific formula. If that’s what you’re saying than I understand. I just got off the phone with my engine builder and he told me that I could hit this motor with 150 shot and cause no problem. ( with the clearances he machined it to). Assuming everything else ‘I’ do is correct.
