Hello, I am currently building an olds 455 for my jet boat and stuck on what ratio rockers I need. I am running a 280 comp cam part number K42-231-4 with Keith Black 60 over stepped dish pistons and stock J heads at the moment.
I want to run a roller rocker, most likely scorpion but I need some help on which ones. If anyone has any experience or info that would be great. Thanks!
