Why are 318's low HP and torque?

Stock compression height is 1.720. You can get some stock replacement 4 eyebrow type pistons with a 1.741 compression height. That might not sound like much, but it makes a difference.

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)
