Cylinder pressure? Help.

Dan,
good luck on trying to figure out DCRs using Hughes cams.I just went through this with Tim and there was no way they were going to either give the actual degree timing of the events or the advertised duration of their cams.They will only give out the .050" events which do you no good in figuring DCR. You need to know exactly when all the valves are closed.
I don't know what you are building but if you go to "wallace racing/engine calculators" you will find a huge amount of info and calculators.
I will be using Comp Cams Extreme Energy/High Lift cams which take advantage of the larger lifter diameter of the mopar lifters, for what that's worth.
