changing IVC @ .006 by 2 degress changes DCR by .07, which is pretty much nothing.
No **** we all want real life measured numbers, but it isnt practical for planning out your engine, there is always going to be a margin of error anyway, Do you think if you plan it out to 8.5 DCr that when you get all the parts and install it all its actually going to be dead on? It wont ever be, there are too many parts in play that all have slight tolerance imperfections.

But seriously, yeah, maybe I'm nitpicking. And we can't control all aspects, but all these "nothings" when all added up can actually account for noticable differences. Like some people said, my extra degrees of advance that came with my cam was nothing...then add in the nothing for not accounting for real world duration numbers...and add in the nothing that is the incorrect bore size in Piano Prodigy's spreadsheet...then add in the nothing for whatever else we can come up with.... Does that make sense? Be as accurate as possible with what you know, and the end result tends to be closer to what you want.

The OP says it is on a LSK lobe so I just matched up what the LSK chart says for those durations, thats as close as we can get without having real .006 specs in front of us. Sure it will probably vary a small amount from there.

99 per cent of the quench talk on this site of BS unless you really know what the pistons are as far as in/out of the deck and really measure it yourself. People are assuming numbers that they did not actually measure so at least make sure you know if your pistons are .005 in the hole or maybe .025 out of the hole because I have seen that on engines lately where both customers thought they were about .008 out!
