ultimately i dont want to loose mph-actually i was thinkin by shortening the duration itll build more torque(and as equally important-at a lower reving range)because if valves are open longer cylinder pressure will be less.if thats the case then would i be correct in saying peak power(and fastest quarter times)has a certain trade off between more duration which will bleed off cylinder pressure and less duration which will increase cylinder pressure with a 10:1 compression motor?bottom line...with the current combo of the car,what would be optimum duration number if i was to taylor converter to cam(because i get one free adjustment on converter)but not to rev beyond 7000 rpm.keep in mind i have a plate system,so i know activation will instantaniously jump rpm of motor but honestly im not sure how much it will on a 250 shot............
