There is one thing you have to understand about an L-100 cam. It is a dual pattern cam, intake 246 @.050 and ex 235 @ .o5o" and 360 net lift. When I first saw this I doubted it could be driven on the street in a heavy vehicle. However, the engine was installed in a 5500 lb ambulance. That was sometime in the late 80's and I became a believer ever since. The Isky 1007B is a very good cam, unfortunately, theonly way to prove one way or another which cam was the best would be very difficult. I've run them both.
