Sorry, I am getting in a frienzy here. Couldn't ya tell.

The other thing I need to stand on my box and preach about is: Stop comparing cams at just .050. That is like comparing two 5000square foot houses to each other, but only comparing the Powder Room. There is so much more to comparing 2 cams to each other then just looking at the .050 numbers. For starters, you need to look at the .200 numbers and the advertised numbers. Be careful with advertised numbers because they will deceive you because some hyd cams advertise at .006, while others advertise at .0045. The .006 advertised is much bigger at the seat in the motor then on paper. This is even more true when Hyd cams have thick oil in them. The shorter the seat number is and the bigger the .050 and .200 number is, the faster the ramp is, and the more power the motor will have at ALL rpm's. It will have a wide band. Remember that early intake opening from big seat timing cams kills and delays cylinder filling and therefore delays the power band. THis is known as reversion in the intake port, and is the worst enemy of filling the cylinder with a dense charge. A port that starts flow late will never catch up. Why not a solid lifter cam that is 15+ degrees smaller at the seat then the Hyd, but 10-20 bigger at .050 and even bigger still at .200? Does this make sense?
