Gary with regard to your question on the cam sprocket holes. I don't know the specifics of your cam but some need to be degreed upon installation and can not just be bolted up as the stock cam was. This is a maybe and maybe not answer because of the lack of specific cam information. If it needed to be degreed and was not then the cam timing could be incorrect. Who installed the cam and were there instructions furnished with the cam? Were these instructions followed during installation?
