I entered ALL my engine specs, and entered all the calculations. It is saying that if retard my cam -3 I will gain 20hp up top with a increase in hp and torque across the rpm range. I have a mismatched combo because the motor is set up for a blower which I no longer have so I'm looking for everthing I can get out of it. It has dished pistons, 64cc head, and a blower cam. I have the motor out of my car now and all torn down so it would be easy to retard the cam.
I always thought that if you retard a cam you will gain up top but loose down low, and if you advance you will gain down low but loose up top? According to desk top dyno 2000 this is not the case. Should I do it and trust the program, or leave it alone?
