Measured some Pro2s today, thought Id share.. surprise they arent as big as claimed. Intake: 0.30892 --- PEAK CAM LIFT --- 0.47882 --- PEAK VALVE LIFT --- Exhaust 0.29204 --- PEAK CAM LIFT --- 0.45266 --- PEAK VALVE LIFT --- Duration is really hit or miss, Duration @ .050 is very small, doesnt quite match up with what they say, but they are fairly smaller then what a lot of people make them out to be., Duration @ .050 for both intake/exhaust is 245/253. Their duration @ .035 seems to match up more with what they claim, 257/266. Sharing information. I came across this because Im repairing a set for a customer over in Singapore, Ive had a really good influx in cam repairs lately and have been able to measure and cam doctor out a lot of unique camshafts. Jun3s/4s, All todas and some other neat stuff.
