    I was going through some of my dads old books (he was a fleet mechanic back in the day) Anyway I found the tuneup specs for a early 60's 702cid GM V12! Judging from the firing order drawings I figure they used the big truck V6 grafted two of them together and made one big ol honkin engine. It has 4 valve covers 2 dist, 2 carbs. Pretty much all the off the shelf parts they could use. Anyone know more about these animals or even have any pics?

    You know I've actually seen one of these monsters in an old 4x4 wrecker that used to come by my work once in a while. I always wanted a better look but he was never there anywhere near my lunch time...
    Pretty cool though, did ya check out the torque specs? Wow!

    That thing's got diesel power and torque numbers. I'd hate to see what it weighs, since the 351 V6's were 900 lbs, and the 637 V8 was 1219. Pretty cool, though.

    No problem!! I'm kinda surprised there are that many people out there who've even heard of the V12's. Some people know about the V6's, Heck my grandpa even had one of them for a while I think. Might have been a I-6 I don't remember. But I whould LOVE too see one of V12's my self!!!. Hmmm, You could mount it in the back end of a pickup mounted "backwards", So the tranny and t-case got stuffed kinda sorta under the cab and.........................
