We use these cams with the Indy rockers and retainers with good results.Choose a good spring with aprox.225 to 250 lbs on the seat and 500 to 600 lbs. open.For best upgrades use 10 degree titanium retainers and 10 degree locks then you can use a little more spring pressure if you want.With the setup we have mentioned you can get a lot of service and life.The cams can be purchased through Comp Cams and Indy.
Ok what I am coming up with is a Comp 23-650-5 cam, Comp 821-16 lifter, and Comp recommends a 925-16 spring? Sorry for asking so many questions but I would like to get all this nailed down so I can order some parts. Then I just need a summit discount code!
