So I am installing some cams on my 2000 mustang since I rebuilt the motor and had it open. I went with a set of Howard rattler cams because I love the sound but I do have questions for people who used them. When it says to raise the rpm to 2500 for 20 mins how would you do that? While it’s parked? Or anything? Is that bad for my motor since it’s gonna be fully rebuilt and it has to be on the first start up. It says I’m not aloud to let it idle but could someone help me on what they did when they installed them or do I just put them in and start it up I do not wanna mess them up my car has been down for 4 months and it’s about to be finished and I do not wanna have to open it up again because of that please help.
