the the other thing that throws me if it is a G= 383 2 bbl with a stick would be odd. I have seen on other websites that G is for 383 2 bbl and 383 hi-po. The K member is still there. The guy I got it from had a 440 auto in it. Looks like someone cut the 4 speed hump out and put in part of an auto tunnel in. It looks crude, definitely not factory looking.
