*the motor in my car has a 82mm (3.22384in.) stock bore.
*the pistons i am wanting to buy are for a 83mm(3.26771in) or 83.5mm (3.278740in) bore.
*If i bored my head 1.5mm (.06356in) how much hp am i looking to get. Since i am making the pistons bigger, and the cylinder walls biiger, what else to i need to buy or do? i plan on some new eagle connecting rods while i am down there.

Thanks my j-body heros!!

you'll get maybe 2 hp if you're lucky from the overbore.
