69 gts 383 block

I was going to say - 383 blocks on their own are not worth much. HP, non-HP, misc years... they might get $150-200 if you have a buyer that wants one. But - a true A body one I'd expect should be able to get a couple hundred more. It's not a needle in a haystack nor do they carry the mystique of a Hemi or something like that.
