Longer Stroke?

I stumbled across this sight while looking for the best ways to moddify an engine I am wanting to rebuild in the near future.

I looked through your suggestions, and searched the forums and found nothing dealing with increasing the stroke of the engine. As well as a few other modifications.

Increasing the stroke should do several things.
1. It would naturally increase the compression ratio.
2. It would shift the torque curve down to where the engine would perform better at lower RPM (sacrificing a higher peak HP at high RPM).
3. Increase the total displacement. (you guys may not like that part so much)

Roller cam/Rockers to reduce internal friction. I don't know if that would improve fuel mileage enough to make it worth it or not but its a thought.
