I wont. Not trying to be an azz but we spend a ton of money and dyno time testing cams for every few HP and really do not want to help another stock racer out. We have to keep stock lift, .462/.473, but can change the event timing and duration around. Typically duration @ .050 can be anywhere from 256 to 278. I use split duration on both the high comp and low comp engines. Low comp engines use more duration and different event timings. The piston to valve in the above deck high comp engines makes cam fitting a real challenge. Also helping these engines out are hydraulic valve trains that allow us to RPM these things over 7200. The transmissions are ultra trick and have custom gears to make use of the power bands we employ. Typical 60' for the high comp car is 1.32 to 1.34. The low comp car goes 1.37 to 1.39. For stockers 60' is everything.You can't or won't divulge cam specs?
That info is what the thread is about. Helping other guys get it done.
