Just a quick update on available and least expensive forged pistons with pricing for the small six.
AutoTec pistons are forged 4032 aluminum alloy.
The alloy is eutectic with around a 12% silicon content so it is durable and keeps a low expansion rate.
The AutoTec pistons are made to order and come with wrist pins that are fitted to the piston.
A flat top piston is $525 for a set of six and $562.50 for a set of dish pistons.

For those that want the strongest piston for Turbocharging, Supercharging and Nitrous or High compression High rpm N/A, BWE offers a 2618 alloy that is heat treated T6.
A flat top piston is $105 each and a reverse dome or dish is $110 each
These pistons DO NOT come with wrist pins. There is a $18 and $30 pin (each) available.
The piston also have the option for a hard anodized friction process for the skirts and a ceramic heat barrier for the top.
Both operations are $40 for each piston.

As with any custom piston, both AutoTec and BWE pistons allow you to take just a cleanup cut off the block deck and head surface.
The pistons are then ordered with the correct wrist pin height, piston top be it dish, flat or dome to get the needed compression ratio.
You also get to decide on the type of piston rings you want to use and are no longer stuck with the old 5/64" ring set.
We have had great success with the BWE ZGS (gapless) rings.
