Thats too bad because he gave up quite a bit believing pump gas CR doesnt matter and the chart that shows a 1-2% gain from raising the CR from say 10:1 to 11:1 which isn’t true.
I'm kinda thinking when we Dyno my 470 I'd like to get a number with the 11.4 & take my heads off to work and mill them down to get 12.4 compression.
Just to see.
