I just got a set of Art Metal pistons. Made in Japan, there L24 and .50mm oversize. The box looks like it's 30yrs old. They came with the pins and ring. There a cast piston. Question, does anyone really know about Art Metal, did they made a good piston? I'm going with the cast becuse I have had problems in the past with forged pistons scuffing on start up. The car will not be used very often and I don't think I'm going to run above 6000 rpm if it ever see's that. I don't want to bore it to a 2800. I do want to keep the block becuse of the numbers. I'm just doing a nice period piece, slight cam SK Mikuni Sports Kit, exhaust and lots of blueprinting and balancing. Thanks

They are one of the best

They are one of the best quality cast pistons available,they used to make the OEM pistons for mitsubishi .No probs with your choice ,just tune the engine correctly and enjoy.
