This is for L8 Apex or anyone with info. I have some cams that came out of a 2001 Roush 4.6L that say Krupp Presta and has two us patent numbers and a model number. I am told they are stock GT cams with Stock lift and duration. However, they appear to have more lift that the "lightning" cams I had. First question is the lift and duration of 2001 stock GT cams. Some of the Mustang boards are saying they are in the .500 neighborhood with duration around 200 degrees at .50. That sounds high to me for stock cams. Second question is the stock lift and duration on a Lightning which I am told is the same as a GT which is hard to believe. Thanks for any input!
