Despite its moderate specs, our new Trick Flow Track Heat 'stick is quite a bit healthier than the factory broomstick cam it replaced. With 1.6:1 rockers, lift comes in at 0.469/0.484 inch intake/exhaust, while duration measures 210/216 degrees at 0.050 inch. LSA is 110 degrees. Chosen in consultation with Trick Flow's Kakiou, the idea was to maintain good idle quality and vacuum--and to allow the car to pass an emissions test. Though not particularly radical, this cam did endow our Z with a nice, rumbly idle.
