340 r.i.p.

Thanks for all the advice. Like I said earlier I have alot to do before I need a motor so I can be patient. I'm gonna put this block in the corner, put the messed up piston and rod on shop table for ash tray and think about it over a few home brews.

Is there much to going to a later roller cam engine? How are those motors balanced and what will I need to change?
