WOW!! That is a great looking ol bolt!! I wish my 66 GMC 960 was in half as good of condition as yours. Im sure the ol girl will not dissapoint you, my 66 has a 292 and had a 4 speed but the previous owner put in a 5 speed and i can sure tell you that she aint afraid of work smile . You got an excellent deal on the ol beast as well, good luck and keep us updated on your progress!!
