    Not entirely certain, but I think his '79 is like the '80 pictured there.

    yes, no OD. Whatever trans came in these before the AOD (C4 or C6?).

    I know the later whales got an upgraded deflector to help guide more air up, I wonder if it could be modified to fit. I donít see why not. I doubt Iíd be able to get one for a box so I might as well try to make another one work.

    They came with the C-4/C5. That is what my 79 ltd S wagon had. Pretty weak especially when put in a wagon and behind a 351 motor. Those transmission could be beefed up to handle the load. Seriously doubt many were.

    Could be worse, the 255 did exist.

    I always thought C4 was the perfect name for that piece of junk given how often they blew up in stock form. They're horribly sloppy things too.

    2.26:1 RAR = 70mph in First gear! (with a C4, anyway)

    I never did successfully explain that concept to someone that my confusion at having to grab Second at 5mph in a certain other vehicle wasn't because that car was a stick shift, it was because its First gear was effectively 2.5 times as deep as I was used to at the time!
