Death comes in many forms.. Death can come by having one's organ exit the body.. or just having the bodily fluids leak all over the floor.. or just close one's eyes.. What form of death are you talking about?
Also depends on the condition of the rest of the car. If rusty, worn interior, etc., it's going to worth a lot less than if the chassis is solid and the interior is OK.
It's not that big a deal to sort out the engine or get a replacement, if you want to keep the car. Of course, if you don't, many people here would be happy to buy it off you.
A rusty Super project can be a $1500 car, or a perfect restored or original one can be a $25,000 car. This one's in between.
I'm guessing, being 44 years old, the seats have been redone at least once, probably not in original Alfa material. This looks like a cheap period US material, which is how these cars were treated mostly over the years, til recently.
This is a pretty garden-variety 1967 US-market Super, early in the 859000 series, which is the last of them we got. No Supers in 1968 or later except unsold 1967s, then 1750 Berlinas in 1969.
