looking to up my comp. as it does not look like the blower will be going back on due to insurance. I would like to know what comp I can safely run on 100oct. Info- currently a 540 with 7.3-1 and brodix BB2X heads. I am going to go to a larger bore size (and crank later) to up the cubes to a 632. What comp. can I change to. Thanks for any info-KELLY
