I have a dead 440 from a 78 3/4 ton 2 wheel drive with motor mount brackets, kickdown, truck oil pan/pickup etc, so should be good there. I have a few radiators laying around, so should be able to make something work there as well. I thought low deck BB would work with the large diameter booster, so should be ok there as well. I'm hoping that between the small block ps brackets in the truck now, the 78 440 ps brackets and the 76 400 ps brackets, I should be able to make something work. The sb in the truck now is AC, as is the 400, Will probably eliminate the AC, as the truck is a small rotary compressor and the big blocks are the older style of course.
