Mark, the cam has a 112 separation. It will idle fairly well at 800-900 with a carb......less with EFI. It will have a cadance, but will make power brake vacuum at idle just fine with 390+ inches. It will smooth up pretty quick off idle, and will do fine with A/C. I would use an electric pop out solenoid if I had A/C and give it a bump at idle. This thread has really hung on.......I figured there were a lot of folks heading for a reliable, smooth, respectable performer that is not a tinker toy. There is no reason we can't drive these FEs into the 21st century! David Jameson's engine will have EFI along with this cam, so we hope for some good feedback from him pretty soon.
