Popping and misfiring

I have a 351w with alum 351c heads. It has high compression. The motor was run with a single holley on alcohol and ran fine in my race car. The motor has sat for a while. I put it in my 57 with a new holley on pump gas and how it wants to pop and mis. Could it be the pump gas dose not have enough octane to keep from firing on compression? Thanks Guy
