Anyone use 1.7 ratio rocker arms???

Sorry this isn't answering your question but I have 1.6 rockers and realized I shot myself in the foot trying to find a cam that is what I want for lift, so I'll have to have a custom cam made eventually
Thanks and no problem. Pretty much anything I build anymore is likely going to have a custom cam anyway, so that's not a problem. I'm just not as familiar with big block Edelbrock heads. I've seen folks run 1.7's on some of the Indy stuff, but I'm wondering what level of clearancing is necessary to run 1.7's on Eddelbrock RPM heads.
