LPE also offers a steel rocker arm stand that locates the rocker shaft assembly and replaces the somewhat fragile stock aluminum piece.
Test 3:
We added a relatively mild LPE hydraulic roller camshaft and Comp valvesprings. Note how the cam raised the torque peak, losing a little torque below 2,800 rpm, but gaining excellent power especially above 4,000 rpm. The combination of the headers and cam was worth 21 lb-ft of torque and a whopping 65 hp peak-to-peak.
Test 4:
All we changed was to the larger LPE hydraulic roller cam, but compared to the stock baseline test, we now have picked up 100 hp!
