Why are 318's low HP and torque?

Do you have a part number for said pistons StrokerScamp?
The standard answer when somene starts a thread abaout building a 'teen is to fit the KB pistons. Some of us builders of 'teens are doing so for finacial reasons. So pistons like the ones mentioned above, would be of great help to folks like me. (Plus the $3-400 360 junkyard core you guys can find anywhere is more like $1200+ here. IF you can even find one)

Same problem here, a 360 rebuilder hard to find and expensive.
