JB, what are you actually looking for? To me it sounds like you are looking for KNOWLEDGE and that can only be had by studying, trial and error + money and time.
There are no shortcuts, there is no simple formula where you enter desired hp and torque and the current timing of the engine in your hand.

The absolute cheapest way is to buy the software I have suggested many times here on RCU and just play around with it.


I'm not trying to be a smart-ass. There just aren't any shortcuts. Nobody can in one post here say what you need to do.
