538177 heads are std '61/'62 heads value ?? $500 rebuilt. If they have "x" and "o" stamped on the center exhaust bosses they are 425a heads so worth more mebby $1000. I recognize the carbs as 3705 Mopar AFB crossram carbs so worth $750 minimum. If the distributor and balancer are indeed sd components they are worth $500 distributor and $1500-2000 balancer. Cast iron sd exhaust manifolds now days worth $3 grand imo. 4 bolt main 425a block worth $1000 bare if a real 389sd block dk value I've never seen one not in a car. Nice engine I have no idea what it is worth together like that I would start at $10,000 probably.
As Tom said and Adecco acknowledged the intake is wrong a real 389sd would have had the 540510 aluminum tripower intake on it.
