mercruiser 2.5/120 engine query
 

Hi there,

I need a definitive answer to this question: I need a new set of piston
rings for a mercruiser 2.5L 120 engine and would like to find an
alternative set of rings to the genuine parts. I am led to believe that
this engine is a derivitive of a Chev or GM unit. The block has GM
stamped on it and the engine serial number is: 2773308.

Can anyone stick their neck out, based on cast iron experience and tell
me what other piston rings would fit this engine?

cheers

Terry

Try Summit Racing or Jags. They can probably cross reference the number.

Only rings, why?

I can give him #'s for pistons, inc. OS sizes...
