Valve relief cc's in TRW flat tops?
I need to know the cc's of the valve reliefs in my p/n L2256F30 TRW flat-top forged pistons (the ones with the 4-valve reliefs). From searching here and other places I've come up with answers ranging from 5cc to 12cc but cant find a definate answer. Does anyone know?
Thanks,
Chris

The coolest thing happened. I went to a search engine, looked up TRW Pistons and found www.TRWaftermarket.com
Then I clicked on "Contact Us" and this page popped up where I could send them an email.
Actually........ here's their phone number
(888) 300-6285
Maybe you can use it?
