I had an older version of Desktop Dyno than the two above and when I got the figures input correctly even it was pretty good. On my 418 stroker it was off by 4 horse power and I think about 5 pounds of torque.For the 69 428 SCJ bored .065 to 440 C.I. it was off by 3 horsepower and 4 pounds of torque. So I felt it was a good program for getting you into the ballpark range of what your engine is. But what you input is important as just one thing off by a little can make quite a difference.
