Re: AMC history (Buick/Jeep V-6)

" Jeep was using the even fire V-6 under 231 inches (226??).
" Kaiser-Jeep continued the engine as it was when they got the tooling
" from Buick with no changes. I'm not sure AMC cast ANY new blocks --
" they used up the stock of parts in a special model CJ (the first
" Wrangler, maybe??) for 1971, and may have used it in the 72 Commando
" as well (don't have my Jeep books handy for exact dates/models). In
" any case, once the stock was used up they didn't make any more, and
" made no changes. When Buick got the tooling back they made the
" changes, more cubes and that awful odd fire crank to begin with. My
" ex wife had a Pontiac Sunbird (78 or 79) when we met with that
" shaking odd fire in it! Timng chain noise and vibration were always
" a problem with it. Don't know when GM wised up and started making a
" new crank for even firing and smoother running. I still don't knwo
" the theory behind the odd firing order to begin with! 

that odd-fire crank was used from the beginning throughout jeep
production.  as the v6 is a sawed-off v8, the crank essentially is
too, so it has a perfect v8 firing pattern - with two holes missing...

btw, the 225 weighed less and had twice the hp of the old jeep f-head
in the cj5.
