360 rebuild issues

The only way to know for sure is to see what they (new pistons & pins) weigh compaired to the stock pistons & pins. If off by a few grams (1-5) i wouldnt sweat it unless yer gonna buzz the heck out of it then go nat's a$$ on ballence,otherwise a few grams will be fine for stock o/h. But also remember lighter is better! Free hp!
