278 Posted January 14, 2009 Report Posted January 14, 2009 I recently made a post about helping to find my compression and what gas to run, I don't know the comp. yet, but assuming I do I have to run race gas because the comp is high can I just drop the dome size to like 21cc domes and keep my +4 timing and run 91 octane pump gas?
