No.


No.....But its no subtle either....What's beautiful about a Hemi, is its resistance to detonation....I would turn the compression up to 12:1 or 13:1 if I was building it as a pro-street or a little raced street car. If you keep the timing in check, you will never have an issue.





Better off getting 12.1 comp pistons then ?


Or stick with 10.5 comp pistons


Thank you for your help every body
