340 WIW.

Don’t know if this is the best forum for this question… I have a 340 I want to sell. Cast date is 9-29-71, it has J heads and a 650 Holley carb. I do have the other numbers if required but, my question is, can someone tell me what it’s worth. It’s all original and apart, don’t have any use for it as I don’t have time to work with it. Can I get some advice.
