Compression truth! Lipstick on a pig?

[wobble]

Kenny, so does that mean us guys with the "14:1" pistons could get away with a half and half mix of race gas since they are only 12.8:1?

Not necessarily.... Look what happens as you tighten up the quench .010" and shave the head .040". This is a 12.5:1 example:

Ya lost me on that one. Kenny, go easy on my little mind!

I'm wondering the same thing Preddy is. It really sounds as though going with a 14:1 off the shelf piston will not require 110 octane as we are told since the compression is only around 12.5. This is for the guys who just dropped in a 14:1 piston. No shaving done on the piston or jug. Am I understanding this correctly, or am I still not getting this.
