    hey guys, just trying to start out on the forums again. i messed up before with a post i never followed through with. hopefully i can help the people that give me help someday. i always thought the 2001-2004 2v 4.6's had 9.5:1 compression but was looking to find out the piston dish cc's and the stock pi head cc's were. been hearing different things everywhere i look. even info on all the 2v piston and head cc's would be appreciated

    I have never officially measured an untouch stock cylinder head, but claims of stock pi is 42cc chamber and 17cc dish pistons. 93-up 2v 4.6l npi heads are 51cc chamber with 11cc dish pistons. All n/a 4.6l 4v pistons are 3cc dish, while the navigators 4v are true flat top. All production 4v heads (to my knowledge) is 52cc. Lightnings pistons came forged with 18cc dish. 03/04 cobra,... not sure?
    Mustangs and licolns piston and rods came full floating wrist pin. Any thing else pre-2000 came pressed pin.

    Any particular reason why knowing the static ratio? What are you planning to build?

    i was debating investing in a 5.0 big bore and was lookin to maybe upgrade heads but at the same time was looking to keep similar to stock compression. i have a 2003 gt with a cobra blower but ended up destroying a shortblock already. replaced it with an 01 longblock but i dont figure its a long term solution.

    thanks for the info, nice to know these things. i was just always under the impression the romeo and windsor engines in new edges had different compression.

    Invest in heads.... (a normal run of the mill built short block is fine)
