I think so. It is important to run some lead for cooling and lubricating purposes. I use Jack Podell's REAL lead octane booster that gives me around 100 good octane. I mix like 12 ounces to around 12 gallons of 93 octane. I am running 10.5 to one in my 1969 Z/28. NO problems with that stuff and I have my timing around 40 total degrees. Sam
