I would appreciate if you can help with identification of the piston at the picture- manufacturer, quality, It is A+1257 +20 and the box on the picture is not original

are they the ones with the big slot for the oil control? fun...

Wide oil slot equals 21251 type. Low compression piston.

thanks..are those good pistons in general??

 

..would be worth it to put them on my built (fast road around 85hp and hopefully 90lbs of torque)?

 

How low is compression?

[ACDodd]

No not good Pistons. Usual Cr from 8.8 to just over 9.0:1 on a stock engine. Ideal for totally standard under 70hp use.
