(L98/LT1) Camshaft/Valvetrain

TPiS has tested hundreds of cams on the Dyno in engines equipped with Tuned Port Injection. We tried many different centerlines, lifts and durations and have settled on a few. You will notice that the lift numbers are modest - this will keep the velocity high around the head of the valve, which improves the combustion process. All of our lobes can be mixed to create the custom cam for your combination.
