56mm piston big bore 066 etc

[Iron.and.bark]

Hey guys,

Still playing with my solo 603.

Looking for a piston alternative.

If anyone has a 066 etc big bore piston, would it be possible to measure the skirt width please

Secondly anyone think of a full skirt (non windowed) 56mm piston I could try?

Cheers.

35mm on the 066 big bore piston.

Your a gentleman, thank you

Partner P100 is full skirted, same pin size as the 066 also.

I bought one of these to try in my 603.

Thank you!

Just checked the 603 piston skirt width, 36mm. So with my enlarged ports probably can't use an 066 big bore.

How does the deck height compare to 603 piston?

Also has a 12mm wrist pin. So will try one of these first I think. Unless the deck height is way out.

Has anyone ever tried welding up scoring on a piston and tried machining it? I know the material is pretty thin for the amount of heat saturation but maybe it's another option?
