hey guys...I got a 70 chrysler 440 with stock open chambered heads..  I want to go thru the engine...  Im trying to find some pistons for it.. I want to bore it .060 and use a gtx cam in it..  one four barrel... ever one is asking me about how many cc's I have... hell, I dont know...  dont even  know how to measure em..  I just want some flatops that will bring my compression up to where it came from the factory..  9.5 9.7. 10.0  in that area.. I just want it the way it came from the factory... any help or advice or easy answers would greatly be appreciated.... if you can help me, please email me privatly to moparmel@gvtel.com

thanks in advance guys  

1970 open chamber heads, 88cc if the heads have not been cut.
Speed-pro sells a 60 over 4 valve notch piston with a 9.4 compression ratio when used with the 88 cc heads.
