CR and pump gas question

Yes, they are. That's exactly what they are doing.

I may, just maybe pull the heads off my junk and make it 11.25:1 just for giggles.

The next engine will be a 386 CID W2 deal and it will be 12:1 on pump gas. On iron heads.

Unless I die first. Which is always possible.

I hope you are right about this.
My current build came out with more compression than I intended . Close to 11...
