Hey dan, i'm loooking to get an iron block s6 (60's to early 70's i suppose) do you know if the early k-frame and s6 mounts will work with the variety of year available?
All slant-6s have the same mount points and bellhousing pattern. All you need for a proper fit is the left and right mount brackets and the oil pan and pickup appropriate to the K-frame you're using. In your case, you'd need '62-'66 A-body engine mount brackets and a '62-'66 A-body oil pan and pickup.
