u need to remember- every mod is a trade off for something
basic boltons are typically trading power and torque for some creature comforts (sound typically). but thats all good because most car guys want a loud ride so they dont see it as a trade off. but thats why we get such restrictive things to begin with. sound and emissions are the biggest reasons we have bolton mods

major mods actually do have a cost you will feel (aside from cash)
small cams can increase both hp and torque. however more duration and more lift will shift the power curve up and will net more peak hp at the expense of low end torque. so we need to know what you want.
you could probably see over 30rwhp increase in a cam alone, but it may take you forever to get there because you have no power down low.

sixxer guys, why dont you throw out some of the cam profiles you have looked at.
