Nice comparison.

so talking about quench.
can i say he went from not good with .055 plus gasket to .050ish with gasket?
just thinking on this to try and save my block as some say to lower my compression.
as far as quench i am either 0 deck or -.005 in the hole.my indys are 49cc chambers and am high 13s to 14 compression ratio.
i am wondering what i would loose going to 12.5 or so if i do next redo

Being from Bend, you don't count in the popularity contest. -1.

Would be nice to have known the cranking compression before and after. Again thanks for sharing.

I've never worried about being poplar, as long as I'm faster than most with similar parts

I understand the diminishing benefits of CR increase as you get into race gas territory but wild CRs will always be linked in my head with wild cams. Nobody with 15:1 compression is running the same cam intake or headers as the guy with 10.5 CR.

Which I guess gets into a dynamic compression discussion which will get in the weeds fast!

For sure the effect a part change has on a specific combo mostly only applies to that specific combination of parts and clearances. At the same time it is always nice to hear about this kind of stuff- especially on a fairly common motor/heads- thanks and I enjoyed the bench racing in the comments too!
