part number needed: 4age bluetop pistons

[cj]

Does anyone know the specs of those pistons?

I was thinking about ordering a custom set from Arias - 81.5mm, 11.5 compression. I know they have the redtop pistons, but i don't have the redtop internals.

This is what Arias are looking for before accepting an order:
• Engine make, model & year
• Bore size
• Stroke
• Rod length (c to c) and material
• Block height
• Compression ratio
• Gasket thickness & diameter
• Wrist pin diameter
• Pin offset and direction
• Application info
• Induction & fuel
• Camshaft specs
(gross lift, lift @ TDC)
• Cylinder head brand
model & part #
• Valve angle
• Combustion chamber CC’s
• Valve diameters & freedrop (valve edge to cyl. head deck)
• and quantities of pistons and hardware.
