DueceCoupe, I have the dragstrip and engine analizer from Performance Trends. Dad uses there pro version, it requires so much input I stick with the regular version. We have found the trick was to go to the dragstrip and get some good clean passes, then using that information calculate what the engine is really putting out. Once I know the true hp it takes to run a given mph, I can build the engine in the analizer to match those numbers. I then use that engine as baseline and build from there. It works pretty well, I used the baseline engine and sent it to the dragrace analizer, built the truck to match the hp and et. With all the different inputs it easy to get it right on the money.
One thing I have learned, there is no magic cam, intake, or exhaust! To keep it driveable, the low rpm torque is a must. Also, what works on the computer does not always work on the street! Joe
