I thinking of using those in my rebuild. But then I saw that they weight aroun 610 grams!? Can there be balance issue with my new SCAT 9000 crank and fordge i beam rods and can I spin those pistons safely to 6200rpm and 420hp?? Is it worth going to SRP instead?

thanks

 

Yes there will be a balance issue. On the other hand, there will be a balance issue no matter what pistons you use; you'll still have to get the assembly balanced, for best possible results.

Yes those pistons will work fine to that RPM and HP level, assuming this is going to be a 350.

As far as "worth it"..... I can't quite see your wallet or your checking account, and I don't know what you're racing against; so it's pretty hard for me or anyone else to definitively declare "worth it" to you, in this build. But IMHO for a street motor with occasional strip duty they'll be fine. I've used them before plenty of times, and gotten plenty good results.

 

ok thanks
