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.
It's not "all original" if it has a 650 holley. By all original I would expect it to have at minimum, the correct TQ, intake, exhaust manifolds, valve covers and oil pan. If any of those items are missing or incorrect, the value drops in my opinion. A good bare 72 STANDARD bore 340 block is worth 300-500 in my area. Your results may vary.
