I have a set of used weisco pistons piston and eagle rods for sale. They are 81.5mm 8.5:1cr. The motor didn't smoke and had good compression before the partout. Rings are still on them if you want to keep it real budget. The pistons have a bit of wear marks from being used but nothing major that would make me not reuse them.
