Whats the value of a ls6 454?

[bisquik65]

I have a 1970 chevelle ls6 454 it is still standard bore with the stock crank turned to 10-10. This engine was rebuilt in 1983 as the car was being tested it lost control at about 90 mph and spun into a used car lot . It totaled 9 cars including itself. I bought the engine from a guy who was going to put it in a model t f**d but gave up on it. Motor was a basket case in a basement and was told $500. for it. 1 hour later i was broke but i have a great motor in my 65 biscayne 2dr 4 spd bench bb clone. Would like to know what the motor would be worth in that cond. Thank you Erick
