Since its a street car I am guessing it will be pump gas ? Whats the pump in your area ? I can find 93 at some stations in my area but most are 92. Course I would keep that in mind when picking a cam. Or have a good cam person or company spec a cam for your combo as that's what I did. I had Dwayne Ported spec a solid flat tappet for my pump gas combo and its nice to know I can pull in any station in my area and gas up and the car will run good with no detonation. Good luck with it. Ron
