11.5 to 1 compression stock lq9
I have a 03 escalade lq9. I was wondering if I could keep the stock 317's and mill them to achieve 11.5 to 1. Would I have to start with 243's? I am not sure of cam selection, though it would be mild, dd, street driving. I don't understand PTV clearance enough or changing combustion chamber. I read some cars run 12.1 compression on 93 pump gas. Any suggestions?
Thanks
