    I need someone look up a cylinder head casting # and let me know what these heads are.

    Casting # 14102193

    All I have been able to find out so far is that they are an 87-newer TBI head. I'm needing to find out engine size, valve sizes, cc, what vehicles they were used in, etc.

    Thanks

    TTT .. somebody has to know something about these ..

    I looked them up on mortec and a few other places and so far can only find that they are SBC TBI heads .. but even then there's confilicting info on if they're 350 or 305 and years of use and none of them list applications, valve, or cc sizes ..

    anybody??

    I was asking the same thing! I think they have to have larger chambers because they're TBI and they didn't have super high compression, something 8.5 or the like.

    Reviving an old post here. (Found it with a search!) /forums/images/graemlins/wink.gif

    Does anyone out there know the chamber size on these heads? (Casting number 14102193). I've searched all the sites I could find on the net, but none of them list the chamber size for these heads.

    Alright, let us in on your secret - where'd you find that? /forums/images/graemlins/ears.gif......I just searched for 20 minutes and found all that info except for the chamber size. /forums/images/graemlins/shocked.gif /forums/images/graemlins/crazy.gif

    Well basicly I just made an educated guess as far as the cc issue goes.
    As far as I know all STOCK 350 TBI heads are 76cc. 8.2 to 1 CR
    All Stock 305 TBI heads are 58cc 9.3 to 1 CR
    I have worked on quite a few TBI engines and have never seen any other STOCK cc head than either 76 or 58 cc.
    There are some other heads used on some performance crate EFI engines that are 64cc but these were never used on a Stock TBI applications. they also have a diferent number.
    My info says 14102193 heads are a OEM standard port EFI head.
    If anyone has more info please post it
    Here's a good page:http://www.73-87.com/chevy_ids/sbcid2.htm
    Lots of good SBC ID stuff there.

    Sounds like you went through the same process that I did. /forums/images/graemlins/wink.gif I'm amazed that no one seems to have published specs for those heads. /forums/images/graemlins/shocked.gif There are only a few million of 'em out there. /forums/images/graemlins/eek.gif

    Thanks for the info Thunder. I dropped a PM to 4DiggerDan. He works at an engine shop and may be able to give us the final word on this. /forums/images/graemlins/cool.gif
