Re: 6.9 Piston Weight

Crank well at a guess its over 40kg probably closer to 50. As I said standard cast pistons for a 292 Chevy 6 are over 900 grams thats why I went with 250 forged at 488 grams.

Re: 6.9 Piston Weight

Give an idea my cast 292 Chevy pistons are 920 grams. Forged Ross 250 pistons are 488 grams . Forged 292 were around 580 something. That's why 250 pistons but need longer rods to use.

Re: 6.9 Piston Weight

Have it somewhere . Old pistons are sitting in my brothers garage in Perth. But they are attached to the rods. From memory they were close to 900grams where quiet heavy forged pistons rods are beefy...
