1970 corvette 454 390HP worth?

[wheelhop]

I bought a similar low miles 1969 - 427 / 400 horse motor a few years back and sold the exhaust manifolds for $500 to $600. I tried to sell the motor (no intake) fairly complete never apart for $3500 to $4000 but did not get much interest. Finally sold it to a buddy for $2500 approximately. Although it would be nice to keep it together, I think you'd do better selling everything separately. Maybe try to market it on a corvette site or forum?
Too many guys going to LS motors nowadays.
That's my .02 cents hope it helps.
