rebuilds

[smigle]

I need to rebuild my engine and i want to boost it and was wondering if when boosted u need forged crank, rods, pistons. I only plan on maybe at the max 9lbs but will stay at 6lbs. Would just a good set of forged pistons and a good tune hold up for a long time or what?

I would at least get forged pistons and rods, but the crank can stay cast. The block will split before a cast crank will break.
