Engine + 365 5-speed tranny. I think it is a bit expensive. The Weber head is desirable but new carbs would be another $1000 but I don't know how to value the 365. They no longer available and their substitutes seem to be rare. For example, it seems that NG3s are pretty rare nowadays. I think that 395 (only 2 spider gears and so are less desirable) are pretty hard to find as well.
In the end, the value of something all depends on what somebody is willing to pay it.
